Answer 1

a. The volume is multiplied by 4

b. The volume is doubled

Step-by-step 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.
