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=(201)/(\pi)`

`r=8`

now, we can find circumference

`C=2\pi r`

`C=2\pi *8`

`C=50.2654 in`

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