How do you find the formula of a half circle?
Alik [6]
Full circle
Circumference = 2*pi * r 
Circumference = pi * d 

Area = pi r * r = pi * r^2
Area = pi d^2 / 4

Half circle
Circumference = pi * r
Circumference = pi * r / 2

Area = pi  r^2 / 2
Area = pi d^2/8

The answer depends on what you are looking for and what you are given. But those are the only common formulas I can think of at the moment.
