Question

A cylindrical vase has height 17 inches and radius 3 inches.

Suppose a second vase has double the radius but the same surface area. What is the height of the vase?

Answer 1

Answer: 4.25 or 17/4 is the height

Explanation:

V=pi*r^2*h

We set them equal to each other and solve for h

pi*3^2*17=pi*6^2*h

h=9*17/36=153/36=4.25=17/4
