Question

it has been established that ratio of circumference of a circle to its diameter is always constant equal to pie.if radious of circle is given by r. Find the formula for the circumference of the circle....​

Answer 1

Answer:

Okay, piece of cake?

Circumference/diameter = constant and is given as π (read as pi).

It's not pie to eat :D

Ohkay again?

C/D = π

⇒ C = π D

We know that radius = D/2

R = D/2

⇒ D = 2R

Substitute this value :

C = π D

⇒ C = 2 π R

This is the required formula.
