# Annulus Area Calculator

The ring-shaped object is called as the annulus (i.e.,) the area surrounded by two concentric circles. It can also be termed as annular. The given below is the annulus area calculator to calculate the annular area with ease. This tool performs annulus (annular) area calculation based on the inputs of the radius of the outer circle, the radius of the inner circle and area of the annulus. With this tool, you can input data and get outputs in different units.

### Example:

Calculate the area of anulus in which the radius of outer and inner circles be 15 cm and 12 cm.

#### Solution:

A = 3.14159 x (15^{2} - 12^{2})

= 254.4690 cm²
