Question

The radius of a cone-shaped tank is 4 feet less than its height. If the height of the tank is (x - 3) feet, the expression below shows the volume of the tank. 1/3 π (x - 7)^2 (x - 3)
What does the factor (x - 7)^2 represent?

The square of the radius of the circular base of the tank
The square of the height of the tank
The area of the circular base of the tank
The area of the curved sides of the tank

Answer 1

From this statement,

"The radius of a cone-shaped tank is 4 feet less than its height."

and this statemnt,

"the height of the tank is (x - 3)"

what is the radius in terms of x?

Answer 2

I have no clue

Answer 3

What is x - 3 minus 4?

Answer 4

x - (-1)?

Answer 5

x - 3 - 4 = x - 7
The radius is x - 7

Now the question is what does (x - 7)^2 represent?

Answer 6

The radius i guess?
