Question

A sphere has a radius of 4.5 cm. What is the volume of the sphere? Round your final answer to the nearest hundredth.

Answer 1

Answer: 381.70
step by step equation: v= 4/3 pi r^3 = 4/5

Answer 2

The equation for the Volume of a Sphere is:

V =
`(4)/(3)`πr²

• V= volume
• r = radius

You 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 =
`(4)/(3)`π(4.5)²

↓

V =
`(4)/(3)`π × 20.25 or V=
`(4)/(3)` × 20.25π

↓

V= 27π (plug this into your calculator to get your numerical value)

V≈ 84.82
