Will give if answer is right

I got 17.99 inches

706.86 sq ft. (or 706.5 sq ft if 3.14 is used as pi)

Step-by-step explanation:

the formula for the area of a circle is πr2^. We know our diameter is 30 ft, and since radius is half of the diameter, that means our radius is 15 ft. Now we plug this into the formula, which would be 3.14x15^2. type this into the calculator to get our area of 706.5 sq ft.

hope this helped!!!
