How to find the volume of a cylinder - SAT Math - Varsity Tutors

The formula for the volume of a right cylinder is: V = A * h, where A is the area of the base, or πr 2. Therefore, the total formula for the volume of the cylinder is: V = πr 2 h. First, we must solve for r by using the formula for a circumference (c = 2 πr): 25 π = 2 πr; r = 12.5. Based on this, we know that the volume of our cylinder ...
