The formula for area of a circle can be found by using a parallelogram explain the way to derive the formula
expeople1 [14]

Step-by-step explanation :

  • The base and height of the parallelogram describe the parts of the circle.
  • Let us consider B as base and H as the height of the parallelogram.  Base b is equal to half of the circumference of the circle.
  • To determine the area of the circle, substitute r for h and πr for b in the area formula by considering r as the radius of the circle.
  • Therefore, the formula to find the area of a circle is πr² square units.
