The formula to calculate the volume of a cylinder is V = πr^2h, where r is the radius and h is the height.
First, we need to find the radius of the cylinder. The diameter is given as 16 inches, so the radius is half of that.
Radius (r) = 16 inches / 2 = 8 inches
Next, we can substitute the values in the formula:
V = 3.14 * (8 inches)^2 * 7 inches
Simplifying:
V = 3.14 * (64 inches^2) * 7 inches
V = 3.14 * 448 inches^3
V ≈ 1409.12 cubic inches
Therefore, the volume of the cylinder is approximately 1409.12 cubic inches.
