The circumfrence of a circle is 16TT

The formula for a circumference of a circle is: C=2π r

and we are given the answer as

C=16 π

Therefore we know that 16 is from the combination of multiplying 2 and r

So to find r we do the opposite of what is done. The opposite of multiplying is dividing, therefore:

16/2=8

therefore r = 8

The formula for the area of a circle is: A=πr^ 2

Since we know r = 8 we just sub it into the equation

A = π*8^2

A=64 π or (assuming you want π to two decimal places: 3.14 then) 200.96
