Area of a circle

Lets learn the area of a circle formula in today's learning.

Circle is one of the geometrical shapes formed by infinite points that are equidistant from a fixed point.

Area of a Circle (A) = π.r2

Where r- is the radius of the circle

Alternate formula

A = π.d2/4 Where d- is the diameter of the circle.
