A sphere has a radius of 4.5 cm. What is the volume of the sphere? Round your final answer to the nearest hundredth.
The equation for the Volume of a Sphere is:
V = [tex]\frac{4}{3}[/tex]πr²
V= volumer = radiusYou have been given the radius of 4.5 cm, so all you have to do is plug this information into the equation and solve!
V = [tex]\frac{4}{3}[/tex]π(4.5)²
↓
V = [tex]\frac{4}{3}[/tex]π × 20.25 or V= [tex]\frac{4}{3}[/tex] × 20.25π
↓
V= 27π (plug this into your calculator to get your numerical value)
V≈ 84.82

x = 5 makes 2x≤ 10 true but not 2x < 10 because "≤" means less than or equal to, which means 2x would be the same as 10, so 10 ÷ 2 = 5, x = 5.
Answer:
Step-by-step explanation:
2x ≤ 10, when x = 5
2(5) ≤ 10
10 ≤ 10 (10 is less than OR equal to 10)
2x < 10, when x = 5
2(5) < 10
10 < 10 (10 is less than 10) - that is false
x = 5 does not makes 2x < 10 true because 10 can't be less than 10.

A net of a square pyramid is shown below. 5.95 cm 5.1 cm What is the surface area, in square centimeters, of the pyramid.
Answer:
86.7
Step-by-step explanation:
L x W = 5.1 x 5.1 = 26.01
B x H ÷ 2 = 5.1 x 5.95÷2 = 15.1725
15.1725 x 4 = 60.69
60.69 + 26.01 = 86.7
The surface area of the square pyramid is 92 square centimeters.
The given figure is a square pyramid.
We have to find the surface area.
Surface area = a² + 2a√(a²/4 + h²)
a is 5.1 cm and h is height which is 5.95 cm.
Surface area = 5.1² + 2(5.1)√(5.1²/4 + 5.95²)
=26.01 + 10.2 √(26.01 /4 +35.4025)
=26.01+10.2 √6.5025+35.4025
=26.01+10.2√41.905
=92 square centimeters.

157 yards
314 yards
100 yards
1962 yards
Answer:
A.
Step-by-step explanation:
A fence is needed for the circular field.
Circumference is basically perimeter but for circles.
Knowing this information, we can use the formula for circumference.
C = [tex]\pi[/tex]d

Answer:
A: 1.5
B: A = n/1.5
C: This means every bowl you make, you would need 1.5 pounds of clay.
Step-by-step explanation:
A: The constant of proportionality is otherwise known as the slope. The formula for the slope is [tex]y_{2}[/tex]-[tex]y_{1}[/tex] / [tex]x_{2}[/tex]-[tex]x_{1}[/tex] (rise over run.) Lets plug the values in.
4.5-0 = 4.5

4.5/3 =1.5
B:
A = n/1.5
C:
The point (1,1.5) is representing the x value, the number of bowls, and the y value, the amount of clay in pounds.
This means every bowl you make, you would need 1.5 pounds of clay.
Teresa worked for 13 hours each day for 5 days. Then the next day she worked 9 hours. How many hours did Teresa work in all?

Answer:
Radius= 8.99 mm (9 mm)
Step-by-step explanation:
We use the formula for the volume of a cone which is
1/3 pi ×(radius)^2 *height
932.58 = (pi) × (11) ×(r^2/3)
Radius^2 = (932.58×3) / (11pi)
= 80.96m
Radius= 8.99mm
Answer:
volume= 1/3πr²h
932.58=1/3×3.14×r²×11
3×932.58=34.54×r² ×3

2,797.74 = 34.54×r²
34.54. 34.54
√r²= √81

Nine years ago, Katie was twice as old as Elena was then.
Elena realizes, "In four years, I'll be as old as Katie is now!"
Elena writes these equations to help her make sense of the situation:
[tex]k-9=2(e-9)\\e+4=k[/tex]
If Elena is currently years old and Katie is years old, how old is Katie now?
Answer:
Given that Elena is currently e years old and Katie is k years old. Now, nine years ago, Katie was twice as old as Elena was.
So, k - 9 = 2(e - 9)
⇒ k - 2e + 9 = 0 .............. (1)
And, in four years, Elena will be as old as Katie is now.
So, k = e + 4
⇒ k - e - 4 = 0 ............... (2)
Therefore, the equations (1) and (2) matches the conditions. (Answer)

It is asking for 3 numbers greater than 0.39, with three in the tenth place (0.x000) that is less than 1. By adding a number in the thousandth place to 0.39, we automatically make it larger. Adding more digits will make it slightly larger, as long as it isn't a 0. All 4 answers I have provided are correct, however, I would just use the first 3 for your question.

The mode will definitely increase since it will change from 78 to 85
The mean will definitely increase because it will change from 82.6 to 86
The median will increase because it will change from 81 to 83
The range will remain the same Highest - lowest score will not change.

The volume of this cone is 1,017.36 cubic inches. The radius is 9 inches. What is the height of this cone?
Answer:
Step-by-step explanation:
The radius of cone = 9 cm
Step-by-step explanation:
Formula : Volume of a cone = , where r= radius , h= height of the cone.
Given: Volume = 1,017.36 cubic centimeters
h = 12 centimeters
Substitute these values in formula , we get
Hence, the radius of cone = 9 cm
