Question

What is the volume of a sphere with a diameter of 2.8 cm, rounded to the nearest tenth of a cubic centimeter?

Answer 1

11.5 cm^3

Explanation:

The volume of a sphere is (4/3)(pi)(r^3). To find the radius, divide the diameter of 2.8 to get 1.4. Then plug it in to get 11.49. 11.49 rounded to the nearest tenth is 11.5 cm^3.
