Enter in the radius of the sphere below to calculate the surface area of a sphere and use the formula for calculating the surface area of a sphere given below to work backwards if you have the surface area of a sphere and are trying to solve for the radius of a sphere. Also ... Intuitively, since the radius remains a constant for just the surface area (i.e., you are not adding up the infinitesimally thin "layers" of the sphere, just the most outer one), the radius differential and integral is unnecessary, thus making the integral $$ A = R^2\int_0^{\pi}\int_0^{2\pi} \sin(\phi) \, d\theta d\phi \; \;\small(2)$$Spherical geometry is the study of geometric objects located on the surface of a sphere. Spherical geometry works similarly to Euclidean geometry in that there still exist points, lines, and angles. For instance, a "line" between two points on a sphere is actually a great circle of the sphere, which is also the projection of a line in three-dimensional space onto the sphere. However ... I believe it follows from this formula for spherical area of quadrangles on Wikipedia that the area should be $$ 4 \arctan\left(\sin\left(\frac b 2\right) \tan\left(\frac \lambda 2\right)\right), $$ assuming that the radius of the sphere is 1, where $$ \lambda = \arccos\left(\frac{\cos(a) - \sin\left(\frac b 2\right)^2}{\cos\left(\frac b 2 ...This tutorial offers a clear and comprehensive guide to finding the surface area of a sphere, a fundamental concept in geometry.

The excess (A+B+C) - 180 is in fact directly proportional to the spherical area of T. If we measure the angles in radians, then we have the precise assertion:Spherical cap. An example of a spherical cap in blue (and another in red) In geometry, a spherical cap or spherical dome is a portion of a sphere or of a ball cut off by a plane. It is also a spherical segment of one base, i.e., bounded by a single plane.A sphere is defined by three axes, x-axis, y-axis and z-axis. The region occupied by a circle is simply an area. The formula of the area is πr2. A sphere has a surface area covered by its outer surface, which is equal to 4πr2. It does not have any volume. The area of a sphere is always expressed in square units, like m 2, in 2, cm 2, yd 2, etc. The volume of a sphere is the total amount of capacity immersed in a sphere that can be calculated using the volume formula for the sphere which is V = (4/3)πr 3.
