Question

When formula gives the relation between the circumference and the diameter of a circle ?​

Answer 1

Step-by-step explanation:

Relationship Between Diameter and Circumference

If you know a circle's diameter, you can calculate its circumference with this equation: Circumference = diameter times pi (3.14).

Answer 2

Step-by-step explanation:

relation between the circumference and the diameter of a circle

circumference =2πr

where r= radius

and we know that

diameter= 2r

then put 2r=diameter in circumference formula

then

circumference=πdiameter

P=πD

where

P=circumference

D=diameter
