1. Calculate for the volume of the original cylinder using the equation,
V = πr²h
where V is the volume, r is the radius, and h is the height
Substituting the known values,
V₁ = π(9 in)²(12 in) = 3053.63 in³
2. Do the same for the cylinder with the increased radius,
V₂ = π(9.03 in)²(12 in) = 3074.02 in³
3. Lastly, determine the difference between the two volumes through the equation,
d = V₂ - V₁
Substituting the known values,
d = 3074.02 in³ - 3053.63 in³
d = 20.39 in³
