A pool company will install a round swimming pool in the middle of a yard that measures 40 ft. by 20 ft. If the pool is 12 ft. in diameter, how much of the yard will still be available?:
466.86 ft2
762.32 ft2
686.96 ft2
347.84 ft2

yard 40*20 = 800
pool pi*(6^2) = 113.04
yard  pool
800  113.04
686.96
