Q:

Can someone tell me what the formula of problem would be? and answer/explain how you got that answer.

Accepted Solution

A:
Answer:Area_shaded  = 2543.742 ft^2 Step-by-step explanation:First we find the area of the external triangleA_triangle = base*height*0.5A_triangle = (92 ft)*(84 ft)*0.5 = 3864 ft^2Then we find the area of the pool (circle)A_circle = pi*radius^2A_circle = 3.1416*(20.5 ft)^2 = 1320.257 ft^2The area of the shaded region Area_shaded = A_triangle - A_circle Area_shaded  = 3864 ft^2 - 1320.257 ft^2 = 2543.742 ft^2
