6. A circular swimming pool has a diameter of 24 ft. and a water height of 3.5 ft. A pump can fill the pool at a rate of 1.2 ft cubed (9 gallons) per minute. About how long it will take to fill this pool ( in hours)?

A. About 15 hours
B. About 1300 hours
C. About 88 hours
D. About 22 hours

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
