Question

find ratio of the perimeter of a circle to its diameter​

Answer 1

Answer:

π : 1

Step-by-step explanation:

Diameter of circle (d) = 2r

Perimeter = 2πr

              p = π2r

              p = πd

Now, p/d = πd/d

               = π/1

Hence the ratio between perimeter of a circle to its diameter​ is π : 1
