What is the tea of a sphere

4πr2

4 pi r^2

The "tea" of a sphere is not a common term or mathematical concept. It is possible that you may have misspelled a term or meant something else. If you are referring to the "area" of a sphere, I can help you with that.

The formula to calculate the surface area of a sphere is:

A = 4πr^2

Where:
A is the surface area of the sphere,
π (pi) is a constant approximately equal to 3.14159, and
r is the radius of the sphere.

To calculate the surface area, you need to know the radius of the sphere. If you have the radius, substitute it into the formula, square it, multiply by 4, and then multiply by π. The result will be the surface area of the sphere.
