Question

What is the volume of a sphere with a diameter of 32.5 m, rounded to

the nearest tenth of a cubic meter? (PLEASE ROUND)

Answer 1

≈17974.2 m

Explanation:

\text{Volume of a Sphere:}

Volume of a Sphere:

Round to the nearest tenth

Answer 2

Explanation:

Givens: d = 32.5 m

Formula: V = 4/3 pi r^3

Solution

r = d/2

r = 32.5/2

r = 16.25

V = 4/3 * 3.14 * (16.25)^3

V = 17965.05 to the nearest tenth is

V = 17965.1
