Question

18. A soccer ball has a radius of 35 centimeters. To the nearest square centimeter, how much material is needed to make a ball? Use pi = 3.14

Answer 1

`Area = 3846.5cm^2`

Explanation:

Given

`d = 35cm`

`\pi = 3.14`

Required

The area of the ball

A soccer
`ball`has the shape of a
`sphere`. So, the area is:

`Area = 4\pi((d)/(2))^2`

So, we have:

`Area = 4 * 3.14 * ((35)/(2))^2`

`Area = 4 * 3.14 * (17.5)^2`

Using a calculator, we have:

`Area = 3846.5cm^2`
