4) Mrs. Armstrong bought a circular, inflatable, above-ground pool for her family. The pool has a radius of 4.5 feet. Which is closest to the area
of the pool? *
O A) 14.13 ft2
B) 28.26 ft 2
O C) 63.62 ft^2
D) 254.34 ft^2

14.13ft2

Step-by-step explanation: pi=3.14

3.14 x 4.5ft = 14.13ft2

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
