You need to repaint the floor and inside wall of your circular swimming pool. it has a diameter of 16 feet and a depth of 5 feet. what is the surface area that needs to be repainted? (use 3.14 for π.) 1,055.04 ft 2 251.2 ft 2 401.92 ft 2 452.16 ft 2

452.16 ft²

Step-by-step explanation:

The surface area is the area of the cylindrical wall plus the area of the circular floor.

A = 2πrh + πr²

h = 5.  The radius is half the diameter, so r = 8.

A = 2π(8)(5) + π(8)²

A = 144π

A ≈ 452.16 ft²

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
