A cylinder has a height of 7cm.
The circumference of the cylinder is 10pi
Calculate the volume of the cylinder in terms of pi
cm3
Answer:
[tex]175\pi \textsf{ cm}^3[/tex]
Step-by-step explanation:
Circumference of a circle:
[tex]C=2\pi r[/tex] (where [tex]r[/tex] is the radius)
Given circumference = [tex]10\pi[/tex]
[tex]\implies 10\pi=2\pi r[/tex]
[tex]\implies r=5[/tex]
Volume of a cylinder:
[tex]V=\pi r^2h[/tex] (where [tex]r[/tex] is the radius and [tex]h[/tex] is the height)
[tex]\implies V=\pi \cdot5^2\cdot 7[/tex]
[tex]\implies V=175\pi \textsf{ cm}^3[/tex]
can someone please help me
Answer: X=6 AB= 52
Step-by-step explanation:
7x + 10 = 9x -2 (because the sides are equal) & solve.
subtract the 7x on both sides.
10 = 2x -2
add 2 on both sides
12 = 2x
divide by 2
x = 6
Answer:
x = 4
AB = 52
Step-by-step explanation:
The dashes on the line segments AB and BD mean that they are equal in length.
⇒ 7x + 10 = 9x - 2
Add 2 to both sides:
⇒ 7x + 10 + 2 = 9x - 2 + 2
⇒ 7x + 12 = 9x
Subtract 7x from both sides:
⇒ 7x + 12 - 7x = 9x - 7x
⇒ 12 = 2x
Divide both sides by 2:
⇒ 12 ÷ 2 = 2x ÷ 2
⇒ 6 = x
⇒ x = 6
Substitute x=6 into the expression for AB to find the length of AB:
⇒ AB = 7(6) + 10
⇒ AB = 42 + 10
⇒ AB = 52
An airplane travels at a speed of 582 miles per hour to reach its destination in 4 hours. Determine the duration of the flight, if the airplane travels at a speed of 388 miles per hour.
Answer: 6 Hours
Step-by-step explanation:
It takes 6 hours to reach the destination when traveling at 388 mph.
Speed is the ratio of total distance traveled to the total time taken It is given by:
Speed = distance/time
Given that it takes 4 hours to reach a destination when travelling at 582mph, hence the distance is:
582 = distance / 4
distance = 2328 miles
If travelling at 388 mph, the time is:
388 = 2328 / time
time = 6 hours
Hence it takes 6 hours to reach the destination when traveling at 388 mph.
Answer:
the answer is 6
Step-by-step explanation:
speed is the ratio of total distance traveled to the total time taken It is given by: speed = distance/time
given that it takes 4 hours to reach a destination when travelling at 582 mph, hence the distance is:
582 = distance / 4
distance = 2328 miles
if travelling at 388 mph, the time is:
388 = 2328 / time
time = 6 hours

A real estate agent believes that the value of houses in the neighborhood she works in has increased from last year. To test this claim, she selects random houses in this neighborhood and compares their estimated market value in the current year to their estimated market value in the previous year. Suppose that data were collected for a random sample of 8 houses, where each difference is calculated by subtracting the market value of the previous year from the market value of the current year. Assume that the values are normally distributed. The agent uses the alternative hypothesis Ha:μd>0. Using a test statistic of t≈7.496, which has 7 degrees of freedom, determine the range that contains the p-value.
Answer:
The range is [tex]-0.00007 < p-value < 0.00007[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 8
The null hypothesis is [tex]H_o : \mu_d = 0[/tex]
The alternative hypothesis is [tex]H_a : \mu_d > 0[/tex]
The test statistics is [tex]z \approx 7.496[/tex]
The degree of freedom is [tex]df = 7[/tex]
Generally the p-value is mathematically represented as
[tex]p-value = P(Z > 7.496 )[/tex]
Generally from the t distribution table
(Reference -
danielsoper(dot)com(slash)statcalc(slash)calculator)
the value of [tex]P(Z > 7.496 )[/tex] at a degree of freedom 7 is
[tex]P(Z > 7.496 ) = t_{7.496 , 7 } =0.00007[/tex]
So the range that contains the p -value is
[tex]-0.00007 < p-value < 0.00007[/tex]
As part of a survey, 75 people were asked to name their favorite sport. The results showed that 25 of the people named basketball as their favorite sport. What percentage of the people in the survey named basketball as their favorite sport?

Natalie has a budget of $15,000 dollars to spend on tracking devices to study bison. A radio tracker costs $650 and a GPS tracker costs $1400. Natalie wants to buy at least 9 radio trackers and more than 3 GPS trackers. The following system of inequalities represents this situation, where x is the number of radio trackers and y is the number of GPS trackers. x ≥ 9 y > 3 650x + 1400y ≤ 15000
I think its Cheap GPS trackers can be purchased from stores such as Walmart or Target. They can also be purchased from electronics stores such as Best Buy.
This diagram shows a park's walking path in the shaded area.
The outside circumference of the walking path is 50.24 meters and the inside circumference of the walking path is 25.12 meters.
What is the area of this walking path?
Use 3.14 for π.
Enter your answer as a decimal in the box.
Point theif = ban
Answer:
150.72 m²
Step-by-step explanation:
To find the shaded area, calculate the area of the smaller (white) circle and subtract it from the area of the larger circle.
-------------------------------------------------------------------------------------------
Formulae
Area of a circle = [tex]\pi r^2[/tex]Circumference of a circle = [tex]2\pi r[/tex](where [tex]r[/tex] is the radius of the circle)
-------------------------------------------------------------------------------------------
Area of large circle
Given:
circumference = 50.24 m[tex]\pi[/tex] = 3.14⇒ 50.24 = 2 × 3.14 × r
⇒ r = 8 m
Therefore:
⇒ Area = 3.14 × 8²
= 200.96 m²
-------------------------------------------------------------------------------------------
Area of small circle
Given:
circumference = 25.12 m[tex]\pi[/tex] = 3.14⇒ 25.12 = 2 × 3.14 × r
⇒ r = 4 m
Therefore:
⇒ Area = 3.14 × 4²
= 50.24 m²
-------------------------------------------------------------------------------------------
Area of shaded path
area = area of large circle - area of small circle
= 200.96 - 50.24
= 150.72 m²

What kind of triangle has sides that have length 4, 8, and 10? ( the triangle acute, right, or obtuse ?)
Answer:
acute because your a cutie
Step-by-step explanation:
x2 − 15x = −50 A) x = 3, x = 5 B) x = 5, x = 10 C) x = 3, x = −5 D) x = −5, x = −10
Answer:
x = 10 or x = 5 thus: B is the answer
Step-by-step explanation:
Solve for x over the real numbers:
x^2 - 15 x = -50
Add 225/4 to both sides:
x^2 - 15 x + 225/4 = 25/4
Write the left-hand side as a square:
(x - 15/2)^2 = 25/4
Take the square root of both sides:
x - 15/2 = 5/2 or x - 15/2 = -5/2
Add 15/2 to both sides:
x = 10 or x - 15/2 = -5/2
Add 15/2 to both sides:
Answer: x = 10 or x = 5

The table shows equivalent ratios. Find the missing numbers in the table.
What is the answer?
Answer:
C
Step-by-step explanation:
Volume = 0.5 * Base * Height * Length
You have to multiply by 0.5 because it is a Triangular prism
base(b) = 4.1
Height (h) = 7.2
Length (l) = 3.5
Plug in the numbers to the equation below and you get 51.66
