If a circle has a circumference of 43.96 units, what is approximate area of the circle?

Question



Answer 1

The formulas you need are C = 2(pi)(r) and A = (pi)(r^2)

43.96 = 2(pi)r. Now see if you can solve for r. You can probably use 3.14 for pi.

After that, substitute your value for r into A = (pi)(r^2) to compute the area.
