Question

find the diameter and circumference when radius is z cm.​

Answer 1

Answer:

The value of z is 44z /7 cm.

Step-by-step explanation:

Given :

Radius of circle  ( R )= z cm.

As we know that,

Diameter of the circle = 2 × R = 2× z= 2z cm.

Circumference of the circle = 2$\pi$R

                                               = 2× ( 22 /7 ) × z cm.      (The value of $\pi$ = 22/7)

                                               = 44z/7 cm.
