O.K, so...
it is 36 ft high
and it has a radius of 14 ft.
WHATS THE VOLUME???
10 POINTS!

V = πr^2h
i will use 22/7 for Pi
V = (22/7) * 14^2 * 36
V = (22/7) * 196 * 36
V = 155232 / 7
V = 22,176 ft^3

Find the area of the bottom of the cylinder first.
So, Area of circle = πr^2 (That's pi times radius squared) π14^2 = 196π
Volume = Area of base x Height.
So, 196π x 36 = 7056π
Now, use the pi symbol on your calculator and multiply it by 7056. If there's a given value of pi in your worksheet, e.g 3.14 or 22/7, use that value. Otherwise, use the pi programmed in your calculator. Round of to two or three decimal places (depending on what your teacher taught you) , and voila! You got it!

Area of a circle is pi*r^2 so,
3.14 * 7^2 = 3.14 * 49 = 153.9
Multiply this by height
153.9 * 36 = 5539 feet cubed
3.14 * 7^2 = 3.14 * 49 = 153.9
Multiply this by height
153.9 * 36 = 5539 feet cubed

easy, 14squared= 196 X pi= 615.75... X 36 = 22167.1 <---- thats your answer !!!
