If the circumference of a circle is 22c cm, find its diameter. (π as 22/7).

1 answer

The formula for the circumference of a circle is C = πd, where C is the circumference and d is the diameter.

Given that the circumference of the circle is 22c cm, we can write the equation as:

22c = (22/7)d

To find the diameter, we can rearrange the equation to solve for d:

d = (22c) / (22/7)

Simplifying further:

d = (22 * 7 * c) / 22

d = (154c) / 22

d = 7c cm

Therefore, the diameter of the circle is 7c cm.
