See answer below

Volume is basically the area of the base of an object multiplied by its height.

As a cylinder has a circular base we use #A=pi*r^2#

Before even using the formula you need to find the radius which is #1/2# of the diameter

Therefore,

#A=pi*r^2#
#A=pi*7^2#
#A=153.94 In^2#

Know this we can just multiply the area by the height of the cylinder which is 4 inches

#153.94*4 = 615.76 In^3 #
