Question

A sphere has a radius of 4 yards. Find its a. volume and b. surface area. Use 3.14 for π . Round the answers to the nearest hundredth.

Answer 1

a) V = 268 yards³

b) A = 201 yards²

Explanation:

a). The Volume of a sphere is given as; V = 4/3πr³

V = 4/3 X 3.14 X 4³

V = 4/3 X 3.14 X 64

V = 803.84/3

V = 267.9 ≅ 268 yards³

b) The area is given as; A = 4πr²

A = 4 X 3.14 X 4²

A = 4 X 3.14 X 16

A = 200.96 ≅ 201 yards²
