    The formula for finding the volume of a cylinder is: \[V = Base \times height\] \[Base\] represents the area of the circle (which is the base): \[\pi \times r^2\] So here you have: \[(\pi \times r^2) \times height\]

    Pi is 3.14 not 3.12. So what number are you using for pi, or are you using the symbol on the calculator?
