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 over 3π (x - 7)2 (x - 3)

What does the factor π(x - 7)2 (x - 3) represent?

The area of the base of the tank
The area of the curved sides of the tank
The volume of 3 of the same cone-shaped tanks
The volume of 6 of the same cone-shaped tanks

Answer 1

I do not get this one do you get it?

Answer 2

Well, if you take out the 1/3, it would be a cylinder, so what do you think the answer might be?

Answer 3

either c or d

Answer 4

Since π(x - 7)2 (x - 3) is 3 times the value of 1 over 3π (x - 7)2 (x - 3), and 1 over 3π (x - 7)2 (x - 3) is one cone, what do you think the answer would be since π(x - 7)2 (x - 3) is 3 times the value of 1 over 3π (x - 7)2 (x - 3)?

Answer 5

I am really confused srry.

Answer 6

Ok, if you take 1/3 out, it would be a cylinder, so π(x - 7)2 (x - 3) is a cylinder. The cylinder is 3 times the value of a cone, so what would the answer be?

Answer 7

c

Answer 8

Yes, good job!

Answer 9

thank you so much may you help me with another one
