How much water can be held by a cylindrical tank with a radius of 12 feet and a height of 30feet?

Question

how much water can be held by a cylindrical tank with a radius of 12 feet and a height of 30 feet?

A.13,564.8 cubic ft

B.2,260.8 cubic ft

C.33,912 cubic feet

D.54,259.20 cubic ft

Answer 1

cylinder

V = πr²h

V = π12²30 = 13571.68 cubic ft

A is closest. I think your teach used the wrong value of pi.

In fact, using his number, pi = 3.14

If you are going to have answers to 6 digits, you must use pi to 6 digits, not 3!  3.14159 is what he/she should be using.

Tell him/her to study math more.

Answer 2

The formula for calculating volume in a cylinder is pi * radius^2 * height.  You already have the data you need: pi is approximately 3.14, so multiply 3.14 times the square of your radius (12) times your height (30).

Answer 3

This question is looking for the volume of a cylinder.  The formula for that is

TTr^2H  (Read as Pi times radius squared times Height)

Pi = 3.14

Radius = 12   so your radius squared = 144

Height = 30

Multiply 3.14 x 144 x 30 and you get 13,564.8 cubic ft.

The answer is A

Answer 4

Formula : Pi(r2)xh

The nearest answer is A

*Hope This helps*

**Good Luck**

Answer 5

Volume of cylinder = (pi)r^2h

so volume = (pi) x 144 x 30 cubic feet

= 3.14159 x 4320

= 13,571.6688 so Answer A is the closest.

Answer 6

Sorry the hubby is working he can figure out math problems... but my guess is C

good luck.

Hey go with ryan he seems to know
