So before we can find the area, we first have to find the radius. We will do this by using the circumference formula, C = 2πr, to find the radius. Our equation will look like this: 30 = 2πr .
For this, all you need to do is divide both sides by 2π, and your answer will be 4.77 cm = r.
Now that we got the radius, we can solve for the area, which is A = πr^2.
A = π(4.77)^2
A = 22.7529π cm^2 or 71.48 cm^2

nswer:
209.8
Step-by-step explanation:
the bottom is = 11 * 5
two of the sides are 11 * 9.3 / 2 because they are triangles, and then times 2 because there are two of them
the other two sides are 10.5 * 5 / 2 , and the * 2 because there are two of them again.
(11 * 5) + (11 * 9.3 * 2 / 2) + (10.5 * 5 * 2 / 2) =209.8
