In this swimming pool design, explain how to find the area of the pool’s surface.

Subtract the area of the semicircle from the area of the rectangle

Step-by-step explanation:

Hi there!

1) Find the area of the rectangle

Plug in the given side lengths 10 and 8 and solve for the area of the rectangle. Disregard the semicircle.

2) Find the area of the semicircle

Divide 8 by 2 to find the radius and solve for the area of the circle. Divide this by 2 to represent the semicircle.

3) Subtract the area of the semicircle from the area of the rectangle

I hope this helps!

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

the answer to the expression is 83
