Question

A conical tent has a radius of 4.8 ft and a height of 4.8 ft. Doubling which dimension(s) will quadruple the volume of the tent?

Answer 1

Answer:

double the radius.

Step-by-step explanation:

Quadruple means 4 times. So you want to make the volume 4 times larger than it currently is.

This can be a little nasty because both numbers are the same.

V = 1/3 pi * r^2 * h

V = 1/3 3.14 * 4.8^2 * 4.8

V = 115.75296

Now if you double the radius, the volume becomes 4 times larger (or it should)

V= 1/3 * 3.14 * (9.6)^2 * 4.8

V = 463.012

Did that make the original volume larger?

115.75296 * 4 = 463.012 rounded.
