To calculate the area of an annulus, square the outer radius (R²) and the inner radius (r²), subtract the square of the inner radius from the square of the outer radius, and then multiply the result by Pi (π). This gives you the area of the annulus. Annulus Area Calculator Outer Radius (R): Inner Radius…
To calculate the surface area of a cone, multiply Pi (π) by the radius of the base (r). Then, multiply this result by the sum of the radius (r) and the square root of the sum of the square of the height (h²) and the square of the radius (r²). Cone Surface Area Calculator Radius…
