State the formula for the circumference of a circle?
OpenStudy (anonymous):
so first we would have to find half of four right then times it by it then times it by 3.14??
OpenStudy (freckles):
once you can do that just replace r with 4
OpenStudy (anonymous):
circumference = 2*pi*r so circumference =2*3.14*4 = 25.12
OpenStudy (anonymous):
r is the radius = 4
