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).

Perimeter of semi-circle: πr + 2r

Area of semi-circle: πr2/2

Circumference of Circle: 2πr

Area of circle: πr2

Answer 2

Answer:

you can get circumference of a circle by using the formula 2×pie×r provided you should know the value of radius(r) and the value of pie i.e. (3.14or22/7)
