Answer:

12.56

Explanation:

So, the circumference will be 4(3.14), which is 12.56. So, now you can solve for area. By the way, the formula is: C = pi(d) (Just saying)

Anyways, A = pi(r)2. So, with the radius being half of the diameter, you will cut 4 in half. You are now ready to solve.

A = 3.14 (2) (2), which is 12.56 .

Hope this helps! :)
