How to find the volume of a cylinder? need , .

Well I personally do not know the volume of a cylinder but for example if you had a cylinder that the radius(had of the diameter) was 5 and say the height was 13 then you could go on google, safari, etc. and search exactly this (also works with triangles, rectangles, squares, circles, parallelograms, trapezoids, etc. and also with the volume and surface area of triangular prisms, rectangular prisms, etc.) but  any way type in this: what is the formula for the volume(area, Surface Area, etc.)  of a cylinder(rectangular prism, triangular prism) you put in the height and the radius of the cylinder and the answer will automatically pop up if this didn't help(which I really hope it did!!) the I am terribly sorry
