Find the circumference
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
Circumference of Circle: 2πr
Area of semi-circle: πr2/2
Area of circle: πr2
