Question

The radius of a right circular cone is 2 in. By what factor will the volume change if the radius of the cone is multiplied by 3 and its height remains fixed?

The volume will be multiplied by
. Real Answer?

Answer 1

The volume of a right
circular cone increased by a
factor of 25. If the height
remained fixed, by what
factor was the radius

Answer 2

the answer is 9

Explanation:

the volume will be muiltplied by9.

when the radius of the right circular cone is muiltplied by k and the height remains fixed,the volume of the cone is muiltplied by k^2.

in this problem k =3 so k^2=9
