Question

What is the volume of the sphere?

Answer 1

4.19 ft³ (3 sf) or (4/3)pi ft³

Explanation:

Volume = (4/3) × pi × r³

= (4/3) × pi × 1³

= (4/3) pi

= (4/3) × 3.14

= 4.186666667 ft³

Answer 2

V = 4/3 pi or approximately 4.187 ft^3

Explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

The radius is 1 ft

V = 4/3 pi (1)^3

V = 4/3 pi

We can approximate pi by 3.14

V = 4/3 (3.14)

V = 4.186666666 ft^3
