_______________________________

Explanation-:

Circumference of circle =

C = 2 π r

Radius of circle =

R = D/2

Area of circle = π r ^2

Here ,

R = Radius

D = Diameter

π = 22/7 or 3.14

C = Circumference

Given ,

Diameter = 10 cm

To find,

Circumference of a circle


_______________________________

Solution-:

Radius of a circle-: D/2


D = Diameter = 10 cm

Then

Radius of a circle-:

10/2

= 5 cm

Radius of a circle = 5 cm

Circumference of a circle-: 2 π r

Radius = r = 5 cm

π = 22/7 or 3.14

2 x 22/7 x 5

= 44/7 x 5

= 31.42 cm

Circumference of circle-: 31.42 cm
