What is the formula for the perimeter of a sphere?

Answer 1

A sphere is a three-dimensional shape, so it does not have a perimeter. The formula for the perimeter is typically used for two-dimensional shapes like squares, rectangles, or circles. The formula for the surface area of a sphere is 4πr^2, where r is the radius of the sphere.

Answer 2

Well, sweetie, a sphere doesn't have a perimeter because it's a three-dimensional shape. The formula you're probably looking for is the surface area of a sphere, which is 4πr². So, if you want to impress someone with your math skills, just remember that little nugget of information.

Answer 3

In 3-dimensional geometry, the term "perimeter of a sphere" is not normally used.

The closest thing would be the equatorial circumference. Think of cutting a ball (with radius r) in half, and looking at the outline of the cut surface. It is a circle with radius r, and the usual circle formula applies:

C = 2(pi)r

Answer 4

A sphere does not have peremiter. Peremiter is the total length of all the edges, and a sphere does not have edges.

It is not that 3D shapes cannot have perimeter, rather shapes without edges cannot.
