Answer:
The area is 12.56 units^2 (same as circumference?)
Explanation:
Assuming pi is 3.14, the equation for the circumference is C = 2 pi r
Fill it out for the radius (r)
12.56 = 2 3.14 r
12.56 = 6.28 r
r = 2
With the radius, the equation for the area is A = pi r^2
Fill it out for the area
A = 3.14 2^2
A = 3.14 4
A = 12.56
