Question

What is this answer. The circumference (c) of a circle can be defined as C=2pi r,where r is the radius of the circle. The circumference of a circle can also be described as what

Answer 1

Circunferencie can be writen also as a fuction of the diameter of the circle

C = pi*D

Where

D = circunferene diameter

Explanation:

C = 2.pi.R = 2.R.pi

In a circle 2.R = D

So,

C = pi.D
