The answer is 78.46 hope this helps

Answer:

A= 78.4602

Step-by-step explanation:

To find the area of a circle, we would need the radius. We can find that from the circumference.

C=2πr

31.4=2πr

31.4/2π= r

r= 157/10π or 4.99747

Now we can use the radius to find the area of a circle.

A=πr^2

A=π(157/10π)^2

A= 78.4602
