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 $A = π \cdot r^{2}$ $A=pi*r^2$

Before even using the formula you need to find the radius which is $\frac{1}{2}$ $1/2$ of the diameter

Therefore,

$A = π \cdot r^{2}$ $A=pi*r^2$
$A = π \cdot 7^{2}$ $A=pi*7^2$
$A = 153.94 I n^{2}$ $A=153.94 In^2$

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

$153.94 \cdot 4 = 615.76 I n^{3}$ $153.94*4 = 615.76 In^3$
