Question

sa = 4πr² is the formula for the surface area of a/an
answer
o rectangular pyramid
o sphere
o rectangular solid
o right circular cylinder

Explanation:

The formula $SA = 4\pi r^{2}$ is a well - known formula in geometry for the surface area of a sphere, where $r$ is the radius of the sphere. Other shapes have different surface - area formulas. For example, the surface area of a rectangular pyramid, rectangular solid, and right - circular cylinder are calculated using different formulas.

Answer:

B. sphere
