Question

The radius of a sphere is 3 cm. What is the sphere’s volume. Round to the nearest tenth.

Answer 1

113 cm^3

Explanation:

The formula for volume of a sphere: 4/3*pi(usually in 3.14)*radius^3.

So you just plug in the values. 4/3 times 3.14 times 27 which equals to 113.04 cm to the power of 3. You get 27 from 3 cube. Don't forget to write the unite which is cm^3

Answer 2

113.1 cm³

Explanation:

The volume of a sphere of radius r is V = (4/3)πr³.

If the radius is 3 cm and the answer is to be expressed to the nearest tenth, then we get:

V = (4/3)(3.14159)(3 cm)³

= (4/3)(84.82 cm³

= 113.1 cm³
