Answer: 3x^2 - 16x + 15
Step-by-step explanation:
5x * 3x = 15x^2
-7 * 3x = -21x
5x * 1 = 5x
-21x + 5x = -16x
5x^2 - 17x^2 + 15x^2 = -12x^2 + 15x^2 = 3x^2
13x - 7x - 22x = 6x - 22x = -16x
- 4 + 19 = 15

3x^2 - 16x + 15
Answer:
V =150.8 in ^3
V=πr^2h
V = pi * (2^2) * 12
V =3.14159 * 4*12
V =150.7964474 in^3
