Tim has a backyard pool in the shape of two semicircles attached to a square. Each side of the square measures 90ft. Find the area of the pool using pi= 3.14.
The Answer is 14,458.5 but I still can't figure out how to get this ????
Can someone please tell me the proper steps that will give me this result?
THANK YOU in advance!

90x90=8100 This is the area of the square section.
The two semicircles we can consider one complete circle, in which case the area is pi*r^2 where r is the radius of the circle.
pi*(45^2)=6358.5 This is the area of the two semicircles combined.
8100+6358.5=14458.5 This is the area of the pool.

The area of a square is A = lw so multiplying 90 by 90 should give you 8,100 ft. squared.
Two semi circles equals 1 circle so you can just take the measurements of the circle, plug it into the formula for the area of a circle and solve using 3.14 then add it to 8,100.
