Use the formula r = √ (A/ (4π)). The surface area of a sphere is derived from the equation A = 4πr 2. Solving for the r variable yields √ (A/ (4π)) = r, meaning that the radius of a sphere is equal to the square root of the surface area divided by 4π.
WebThe area of a disk enclosed by a circle of radius R is Pi*R 2. The formula for the circumference of a circle of radius R is 2*Pi*R. A simple calculus check reveals that the latter is the derivative of the former with respect to R. Similarly, the volume of a ball enclosed by a sphere of radius R is (4/3)*Pi*R 3. And the formula for the surface area of a sphere of … WebMar 27, 2014 · Find the area of the spherical caps on either side, and subtract it from the total surface area 4 π r 2 For the area of the spherical caps, you can use A = Ω r 2 where the angle Ω is the solid angle (steradians) of a cone whose cross-section subtends the angle θ at the center, given by Ω = 2 π ( 1 − c o s θ) Share Cite Follow
