Answer:
is it a test and what is the lesson name called?
Step-by-step explanation:
Step-by-step explanation:
D. must be the richt answer.
(x - Px)^2 + (y - Py)^2 = r^2
Where P(Px | Py) is the center of the circle.
If you insert one point of the circle, the equation must be true.
The answer is 3.16 ft
The surface area (SA) of the rectangular prism is:
SA = 2lw + 2ld + 2wd
However, the pool is without the top side, so the area of the top side should be excluded from the surface area of the pool. The surface area of the rectangular pool is:
SA = lw + 2ld + 2wd
We know:
SA = 210 ft²
l = 9 ft
w = 10 ft
d = ?
210 = 9 * 10 + 2 * 9 * d + 2 * 10 * d
210 = 90 + 18d + 20d
210 - 90 = 38d
120 = 38d
d = 120/38
d = 3.16 ft
-6 so option D is the answer
