Area Calculator Round Shapes
Use these calculators to calculate the area, perimeter and arc length for various round sided shapes, including a circle, circle sector, circle segment, annulus, ellipse and capsule.
If you would like to calculate the area of a round shapes the please use our Area Calculator for flat-sided shapes .
The calculators are unitless, if you input values in mm the results will be in mm and mm², if you then wish to convert why not use our universal converter.
If you need to calculate the volume of a spherical shape use our volume calculator.
