Question

WILL MEDAL FOR EXPLANATION
The holding tanks are congruent in size, and both are in the shape of a cylinder that has been cut in half vertically. The bottom of the tank is a curved surface. What is the volume of both tanks if the radius of tank #1 is 15 feet and the height of tank #2 is 120 feet?

Answer 1

So because the two half-cylinders are congruent, you can assume that the radius and height are the same on both tanks. Use this formula to find the volume of the half-cylinders.
V= (π r^2 h) / 2
(They will have the same volume.) The formula is the same as the formula for the volume of a cylinder but divided by two (cut in half).

Answer 2

Hope this helps :)

Answer 3

Ok, thank you give me a min to try

Answer 4

Would it be 42411.5008235

Answer 5

How did you get that? can you explain?

Answer 6

V= (π 15^2) 120 / 2 think i did it wrong tho

Answer 7

No you did it right :)

Answer 8

did it come out to be the right answer tho

Answer 9

I think so. I even plugged it into an online calculator. It follows the rules of PEMDAS so it should be right.

Answer 10

Thank you so much!!

Answer 11

Absolutely! Hope you do well!
