the shaded area = area of trapezoid - area of circle

bibby · Answer

C. The area of the shaded section would be the area of the (I assume trapezoid) - the area of the circle.

($$b1+b2\div2$$)*h = (17/2) * 8 = 68
circle area = pir^2 = 4^2pi = 16pi

anonymous · Answer

wait , im confused , how did you figure that out?

bibby · Answer

You step back from the problem and see how to arrive at the answer. If the area of the trapezoid is that whole inside part and we subtract the extra stuff in the middle (circle) we get the shaded portion.

raden · Answer

maybe, u just undertanding that the diameter of circle = the height of trapezoid
