Volume of Spheres Review

Front

What is the formula for the volume of a sphere?

Back

The volume V of a sphere is given by the formula V = (4/3)πr³, where r is the radius of the sphere.

Front

If a sphere has a radius of 8 cm, what is its volume using π = 3.14?

Back

The volume is 2144.7 cm³.

Front

What is the relationship between the radius and the volume of a sphere?

Back

The volume of a sphere increases with the cube of the radius.

Front

How does changing the radius of a sphere affect its volume?

Back

Increasing the radius increases the volume significantly, as volume is proportional to the cube of the radius.
