Question

How does the volume of a sphere with a radius 2 cm compare to the volume of a sphere with a radius 1 cm?

Answer 1

Answer: It is about 29.3 cm larger.

Explanation: The volume of a sphere is 4/3πr^3.

To compare the two volumes, we can simply subtract the smaller volume from the larger one.

(4/3*π*2^3)-(4/3*π*1^3)=29.32153=29.3.
