Answer:
D. 640 m³
Step-by-step explanation:
The height CD of the cone is found using the Pythagorean theorem.
BC² + CD² = BD²
8² + CD² = 17²
CD = √(289 -64) = 15
The volume of the cylinder is ...
V = πr²h
The volume of the cone is ...
V = 1/3πr²h
So, the portion of the cylinder not occupied by the cone is ...
V = (πr²h) -(1/3πr²h) = (2/3)πr²h
V = 2/3(π)(8 m)²(15 m) = 640π m² . . . . . matches choice D
Answer:

Answer:
12*5/6*4 = 40 liters
Step-by-step explanation:
1 1/4
4 fits into five once, leaving 1/4 left making it a mixed number.
Ax^2 + bx + c = 0
x^2 - 5x = 14
x^2 - 5x - 14 = 0
a = 1
b = -5
c = -14
