Circumference worksheets are the worksheet involved in which there are the solved as well as the unsolved problems of the circumference. This worksheet is the best way to understand the concept of the circumference of the circle and its application. This uses the below mentioned formulas for the calculation of the circumference of the circle.

Circumference formula based on the radius of the circle

Circumference of circle = 2 x pie x r

Circumference formula based in the diameter of the circle

Circumference of circle = pie x d (because d = 2r). Here pie = 22/7 or 3.14.

In the problems defined below, we will use the radius based formula



Example 1:- Find the circumference of circle if the diameter of the circle is 980 cm.

Solution:- Given diameter of circle = 980 cm

=> Therefore, Radius of circle = diameter of circle/2 = 980/2 = 490 cm

=> So the circumference of circle = 2 x pie x r = 2 X 22/7 x 490 = 3080 cm

=> Hence the circumference of circle is 3080 cm.
 


Example 2:- Find the circumference of circle if the diameter of the circle is 840 cm.


Solution:- Given diameter of circle = 840 cm

Therefore, Radius of circle = diameter of circle/2 = 840/2 = 420 cm

So the circumference of circle = 2 x pie x r = 2 X 22/7 x 420 = 2640 cm

Hence the circumference of circle is 2640 cm.
