Question

what is the formula of findjng the circumference of diameter
​

Answer 1

To calculate the circumference of a circle, multiply the diameter of the circle with π (pi). The circumference can also be calculated by multiplying 2×radius with pi (π=3.14).

Circumference of Circle: 2πr

Perimeter of semi-circle: πr + 2r

Area of semi-circle: πr2/2

Area of circle: πr2
