d is the forth proportional
a) d = 2*3/1 = 6
b) d = 3*4/0.5 = 24
c) d = b*5/a = 5*b/a

Answer:
9.43 ft
Step-by-step explanation:
First, we need to find the area of the entire circle(shaded & unshaded), which is 12.57, with a radius of 2 ft. Next, we find the area of the white area, and NOT the shaded area, which is 3.14, with a radius of 1 ft. Now, we need to subtract the white area(3.14) from the total area(12.57), which is 9.43.
Hope this helps!
