WebJul 5, 2024 · For a circle, the derivative of the formula for area is the formula for circumference: d/dr ( [pi*r^2)=2*pi*r. Similarly, the derivative of the formula for the volume of a sphere is equal to the formula for surface area: d/dr (4/3*pi*r^3)=4*pi*r^2. I'm positive that these are consequences of Stokes's (Green's) and Divergence theorems, but I don ... WebCircumference of a Sphere Formula: Circumference C = 2πr Surface Area of a Sphere Formula: Surface Area A = 4πr² Sphere Calculations: This section gives the sphere formulas in terms of volume, circumference, and surface area. If sphere circumference is known, then Volume V = (C³ / 6π²) Radius r = C / 2π Surface Area A = C² / π

WebJan 11, 2024 · The formula to find the circumference of a sphere is given by. Circumference (C) = 2\(\pi\)r, where \(\pi\) = 22/7 = 3.141 and r = radius. Surface Area of Sphere. Surface area of sphere is the area covered by the outer surface of the sphere. We know that the sphere is a completely curved shape, therefore the curved surface area is … Circles on the sphere are, like circles in the plane, made up of all points a certain distance from a fixed point on the sphere. The intersection of a sphere and a plane is a circle, a point, or empty. Great circles are the intersection of the sphere with a plane passing through the center of a sphere: others are called small circles.
