4×4=16 (4^2)
16×4=64 (4^3)
64×4=256 (4^4)
So 256 is 4^4
The formula given to us relates circumference with radius but we are given diameter instead. good thing we know that diameter is twice the length of radius so if diameter=28, the radius=14. therefore, using our formula, we can find the circumference:
C = 2(pi)(14)
C = 87.96
and this answer is close to 88 so the answer is A
