Question

The circumference of a circle of diameter ‘d’ is ________ units.​

Answer 1

Answer:

The circumference of a circle of diameter ‘d’ is 3.14d units.

circumference of circle = πd

= 3.14 x d

= 3.14d

pls mark me as the brainliest and thank me

Answer 2

Answer:

The circumference of circle = $\pi$d units  or 3.14 d units

Step-by-step explanation:

The problem is about finding circumference of a circle with diameter  "d"

Given that diameter of circle = d

circumference of the circle = 2 $\pi$r

here r = radius of the circle =  $\frac{d}{2}$    

circumference of circle = 2 $\pi$ $(\frac{d}{2})$

                                       = $\pi d$ units  

                                       = (3.14)d units

                                       = 3.14d units     ( $\pi$= 3.14 )
