What is the exact volume of a cylinder with a base height of 30, and a radius of 13

Volume of a cylinder is \pir^{2}h. This is basically the area of a circle multiplied by the height. You can think of it as congruent circles being stacked on top of each other to create a cylinder. With the given information, all we have to do is substitute the values into the variables

V = \pir^{2}h.
V = \pi(13)^{2}x30
V = \pi x 169 x 30 = \pi 5070

Hope this helps! 
(btw if it asks for "exact" anything, leave the pi. Pi is the ratio of the circumference to its diameter, so not every circle will have a pi of 3.14.)
