Question

A top of a round cake has an area of about 201 square inches what is the circumference of the top of the cake rounded to the nearest inch

Answer 1

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

$201=\pi r^2$

$r^2=\frac{201}{\pi}$

$r=8$

now, we can find circumference

$C=2\pi r$

$C=2\pi *8$

$C=50.2654 in$

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