Answer:
The formula for the area is πr² where r is the radius.
But the radius wasn't given so we have to ring it via the circumference given.
Step-by-step explanation:
Circumference = 87.92
To find the radius;
The formula for finding the circumference is 2πr. Therefore;

So now that we have our radius to be 14 we substitute it into the equation for finding the area
