We know that circumference = 2πr
where r is the radius.
Further, we know that 2r = d (diameter)
and 2πr can be written as 2r × π
=> d × π
= πd
Hence, 2πr = πd
So circumference = πd
Given, circumference = 1256 cm
π = 3.14
=> 3.14 × d = 1256
=> d = 400 cm
Hence, diameter of the circle = 400 cm.
where r is the radius.

π = 3.14
=> 3.14 × d = 1256
=> d = 400 cm
Hence, diameter of the circle = 400 cm.

Hi Mate!!!
Circumference of circle is = π × D
where D is diameter of circle
π × D = 1256cm
D = 1256 / 3.14
D = 400cm
