we are given

A top of a round cake has an area of about 201 square inches

Let's assume radius of circle is 'r'

$A=\pi r^2$

now, we can plug values and solve for r

$201=\pi r^2$

$r^2=(201)/(\pi)$

r=8

now, we can find circumference

$C=2\pi r$

$C=2\pi *8$

C=50.2654 in

C=50in .................Answer
