Find the area of this circle.
A= ?
5 in
Hint: First, plug in the value
of the radius into the
formula for r.
If radius, r = 5in., then we can compute that the area of the circle = 78.55in² or approximately 79in².
Using the formula, Area of Circle = πr²
It is given in the question, r = 5in and as we know that the value of π = 3.142
Now, putting the values from above in the formula of area of circle, we will get:
A = π × 5² = 3.142 × 25 = 78.55
= 79in² (to the nearest whole number).
The space a circle takes up in a two-dimensional plane is known as its area. Alternately, the area of a circle is the area contained within the circumference or boundary of the circle. The sum of the square units inside that circle is another name for it.

Let's do this step-by-step explanation!
[tex]\frac{2}{3}[/tex] × [tex]7 \frac{2}{6}[/tex]
Convert mixed numbers to improper fractions: [tex]7 \frac{2}{6} =\frac{44}{6}[/tex]
[tex]=\frac{2}{3}[/tex] × [tex]\frac{44}{6}[/tex]
Cancel: [tex]\frac{44}{6} :\frac{22}{3}[/tex]
[tex]=\frac{2}{3}[/tex] × [tex]\frac{22}{3}[/tex]
Apply the fraction rule:
[tex]2[/tex] × [tex]22[/tex]
[tex]3[/tex] × [tex]3[/tex]
Mutiply the numbers: [tex]2[/tex] × [tex]22[/tex] [tex]=44[/tex]

-----
[tex]3[/tex] × [tex]3[/tex]
Mutiply the numbers: [tex]3[/tex] × [tex]3=9[/tex]

Answer:
all x are the solution
Step-by-step explanation:
x - 4×3 - 4×(-2x) = 3×3x + 3×4

D.) 4,020 ft2
I NEED this answer in 5 MINUTES!
Answer:
3484 ft²

In the year 2000, the height of an apple tree was
150 centimeters. In the year 2020, the same tree has
grown to 270 centimeters. What was the average rate
of change in the height of the tree from 2000 to 2020?
In other words: On average, how fast was the tree
growing? Include units.
Answer:
(270+150)/(2020-2000)= 21 - average rate of change in the height per year
Answer:
I think to get the average rate you subtract 150 from 270 centimetres you'll get 120 centimetres then subtract 2000 from 2020 to get 20 now to get the rate divide 120cm by 20 and you will get six so the rate is 6 cm per year

What is the best estimate for a length of a car?
Answer:
Yards
Step-by-step explanation: Yards make the most since because the average car is about 3 to 5 yards.
what is the value of y that satisfies the equation below y/2=9
Answer:
y/2 = 9
In order to find the value of y, we must first isolate y by performing inverse operations.
Right now, y is being divided by 2, so the inverse operation of division is multiplication.
So we multiply by 2 on both sides:
y/2 = 9
*2 *2
2/2y = 18
y = 18

Find the volume of the cone. Round your answer to the nearest tenth. A cone is shown. Its height is 9 yards and the diameter of its base is 7 yards.
Answer: 346.2yd³
Step-by-step explanation:
Volume = Area of Base x Height
Volume = πr² x 9
Volume = π(3.5)² x 9
Volume = 38.465 x 9

A team of 13 basketball players needs to
choose two players to refill the water
cooler.
O Permutation; 39
O Combination; 60
O Combination; 78
O Permutation; 156
The selection of the basketball players is an illustration of combination
The number of ways the basketball players can be chosen is 78
How to determine the number of selectionThe given parameters are:
Number of players (n) =13
Players to select (r) = 2
The number of ways the players can be selected is calculated as:
[tex]^nC_r = \frac{n!}{(n -r)!r!}[/tex]
The equation becomes
[tex]^{13}C_2 = \frac{13!}{(13 -2)!2!}[/tex]
Evaluate the difference
[tex]^{13}C_2 = \frac{13!}{11!2!}[/tex]
Evaluate the factorials
[tex]^{13}C_2 = \frac{13 * 12 * 11!}{11! * 2}[/tex]
Evaluate the quotient
[tex]^{13}C_2 = 13 * 6[/tex]
Evaluate the product
[tex]^{13}C_2 = 78[/tex]
Hence, the number of ways the basketball players can be chosen is 78

how many 6/14 feet of rope can you make out of 49/14 peices of rope?
This word problem is another way of saying
How many times can 6/14 go into 49/14
To find this out we divide
(49/14)/(6/14)
We also know that dividing by a fraction is the same as multiplying
=(49/14)(14/6)
=49/6
≈8.16
As we just want how many segments of 6/14 feet rope, we can ignore the decimals/round down getting the answer
Eight pieces of rope can be made our of 49/14 piece of rope.
