The answer depends on what characteristic of a half circle you want to calculate: its area or perimeter or something else.
Area of circle = pi x radius x radius where pi = 3.14159 If radius = 6 cm then Area = 3.14159 x 6 x 6 sq cm = 113.097 sq cm
Area = pi*radius squared
A cone with a radius of 6 centimeters and a slant height of 9 centimeters will have a total surface area of approximately 282.74cm2
If it is a circle you are referring to the Area if the circle would be (pi)x(r^2) and the radius is 6 so the answer would be 36(pi)
