How to use the MathCalc circle area calculator?

Step by step:

  • Enter the radius in the given box.
  • After entering the values, click on calculate, and in seconds, you will see the result.

Example: If you find the area, circumference, and diameter of radius=40.

Step by step:

  • Given: radius = 40
  • Area formula: A = πr²
  • Area calculation: A = π × 40² = π × 1600 = 5026.5482457437
  • Circumference formula: C = 2πr
  • Circumference calculation: C = 2 × π × 40 = 251.32741228718
  • Diameter: d = 2r = 2 × 40 = 80

result:

  • Area: 5026.5482
  • Circumference: 251.3274
  • Diameter: 80
