2 dni temu · The surface area and volume of a torus are quite easy to compute using Pappus' theorem. A torus is a circle of radius \( r< R,\) centered at \( (R,0)\) and rotated around the \(y\)-axis. The centroid of both the surface of the circle and the region enclosed by the circle is just the center of the circle.

1 dzień temu · The area of a corner or segment of a circle can be calculated using the formula: \ [ S = (1 - \frac {\pi} {4})r^2 \] where: \ (S\) is the area of the corner, \ (r\) is the radius of the circle.
6 dni temu · Concrete Slab Calculators. The following functions apply to estimating the amount of concrete, rebar, form boards and water needed for concrete slabs of different shapes: rectangular with squared corners, circular including semi-circle, and polygon shapes from triangular up (e.g., pentagon for 5 sides and dodecagon for 12 sided polygon).
