I believe the one you have selected is correct.
Here is a photo of how I got the answer and what the answer is (Red and blue represent my work, while highlighter shows what the answer is):
Answer:
Step-by-step explanation:
Given
--- base of the tank base
--- height of the tank base
--- height of the tank
Required:
Determine the volume of water needed for 6 inches below the top
First, calculate the area of the tank base.
If the tank is filled 6 inches below the top, this means that the height of the water is H - 6.
So, the volume is:
Substitute 240 for Area and 36 for H
Answer:
15.75 ft^3
Step-by-step explanation:
The volume of a cone is given by
V = 1/3 pi r^2 h where r is the radius and h is the height
We know the diameter is 3 so the radius is 1/2 the diameter or 3/2
The height is 7 and we will use 3 for pi
V = 1/3 (3) (3/2)^2 *7
V = 15.75 ft^3
The answer would be c because if you turn the 285 miles into into feet, and divide it by the number of minutes in 6 hours, you get 4180 ft
