WebNov 4, 2024 · Hence, we find that. Vslice = π(4 − x2)2Δx, since the volume of a cylinder of radius r and height h is V = πr2h. Using a definite integral to sum the volumes of the representative slices, it follows that. V = ∫2 − 2π(4 − x2)2dx. It is straightforward to evaluate the integral and find that the volume is. V = 512 15 π. WebArea formula The area of the annulus is the area of the ring-shaped space between the two circles that define it. In the figure above it is the number of gray square units it takes to fill the annulus. This area is the area of the entire disk, minus the area of the 'hole' in the middle.
