Hi!!
-------------
Since Circumference of a circle = pi * diameter
Given :
Circumference of a circle = 66cm
Let diameter be d.
=) 66cm = pi * d
=) 66cm = 22/7 * d
=) 66cm * 7 / 22 = d
=) 3* 7 cm = d
=) 21cm = d..
Hence diameter of a circle is 21cm.
Hope it's helpful to u.

Circumference = 2Πr
2×22/7 × r= 66
r= 21/2
Diameter= 2r
= 2(21/2)
= 21
2×22/7 × r= 66
r= 21/2
Diameter= 2r
= 2(21/2)
= 21
