Answer

a. The volume is multiplied by 4

b. The volume is doubled

Explanation

a. The volume of a cone with radius r and height h is $\pi r^2 h/3$ . If the radius is doubled, the new volume will be $\pi (2r)^2h/3$ , which is equal to $4\pi r^2h/3$ . This means that the volume is multiplied by 4.

b. The volume of a cone with radius r and height h is $\pi r^2 h/3$ . If the height is doubled, the new volume will be $\pi r^2(2h)/3$ , which is equal to $2\pi r^2 h/3$ . This means that the volume is multiplied by 2.
