Question

the volume of a sphere is found using the formula v=4/3pir^3 The area of a circle is found using the formula a=pir^2 What is the ratio of the volume to the area?

Answer 1

well almost

the ratio is

\[\pi r^2 : \frac{4}{3}\pi r^3\]


dividing both sides of the ratio by

\[\pi r^2\]

you will get

\[1: \frac{4}{3} r\]

or it can be written as

\[3:4r\]

hope it helps
