Find the area of the shaded region
A. 549
B. 1256
C. 707
D. 400
E. 1863

A

Step-by-step explanation:

The shaded area is the area of the outer circle - the area of the inner circle.

the radius of the outer circle r₁ = 40 ÷ 2 = 20m

The radius of the inner circle is r₂ = 15 cm, thus

shaded area = πr₁² - πr₂²

                     = π(20² - 15²) = π(400 - 225) = 175π ≈ 549 → A

answer: slight chance that it will happen
