Question

Find the radius of a circle with a circumstance of 28π

Answer 1

We have the next formula to find the circumference of a circle

`C=2\pi r`

where C is the circumference and r is the radius

In our case we have

C= 28π

we substitute the value in the formula

`28\pi=2\pi r`

then we isolate the r

`r=(28\pi)/(2\pi)=14`

the radius is 14.
