# Curved surface area of sphere calculator

Sure! Here’s how to calculate the curved surface area of a sphere using a calculator:

**Identify the radius (r) of the sphere.****Square the radius: r^2****Multiply by 4π: 4πr^2****Round the final result to the desired number of decimal places.**

That’s it! You can now use this formula to calculate the curved surface area of a sphere using a calculator.

### The curved surface area of a sphere is given by the formula:

**A = 4πr^2**

where r is the radius of the sphere.

This formula represents the total surface area of a sphere, including both the curved and flat surfaces. The curved surface area is the part of the surface that is curved, while the flat surface area refers to the two circular faces of the sphere.

To calculate the curved surface area of a sphere, simply use the above formula with the given radius and simplify the result.
