WebNov 21, 2024 · In this area of a sphere calculator, we use four equations: Given radius: A = 4 × π × r²; Given diameter: A = π × d²; Given volume: A = ³√ (36 × π × V²); and. Given surface to volume ratio: A = 36 × π / (A/V)². Our area of a sphere calculator allows you to calculate the area in many different units, including SI and imperial units.

WebOct 30, 2010 · A "great circle", so called because they are the largest possible circles on a sphere. If you're on a sphere (say, Earth) and you want to go between two points using the shortest path, then a great circle is the path you should follow. This makes them like straight lines for spheres. Or in technical terms, arcs of great circles are geodesics. popular name brand shoes for women
