The volume of gas a balloon can hold varies directly as the cube of its radius. imagine a balloon with a radius of 3 inches can hold 81 cubic inches of gas. how many cubic inches of gas must be released to reduce the radius down to 2 inches?

Two variables, x and y, vary inversely, and x=12 when y=4. what is the value of y when x=3?

The radius of the earth is two times the radius of the moon. what fraction of the volume of the earth is the volume of the moon?
