Answer:
PQ = 20
QR = 15
Step-by-step explanation:
PQ^2 = 16^2 + 12^2
PQ^2 = 400
PQ = √400 = 20
QR^2 = 12^2+9^2
QR^2 = 225
QR = √225 = 15
The volume of the cylinder by definition is given by:
V = pi * r ^ 2 * h
Where,
r: radio
h: height
Substituting values we have:
V = 3.14 * (14/2) ^ 2 * 4.5
V = 692.37 ft³
Answer:
the volume of the pool is:
V = 692.37 ft³

Answers: B, C, F</h3>
Each of these are closed figures formed by straight line segments. Think of fencing in an area (not necessarily a rectangle) using various straight fence sections. The length of each section does not have to be the same.
Side notes:
- Choice A is not a polygon because the figure is not closed.
- Choice D is not a polygon because it is not composed of line segments only. Choice D is an ellipse instead.
- Choice E is not a polygon due to the curved portion.

Answer:
1. A
2. B
3. D
Step-by-step explanation:
Use PEMDAS to solve all
1.
8^2 - 6*2
8*8 - 6*2
64 - 12 = 52
2.
4^2 * 3 + 4 * 2
4 * 4 * 3 + 4 * 2
16 * 3 + 8
48 + 8 = 56
3.
9^2 - 2(5+3)
9 * 9 - 2(8)
81 - 16 =65
