If the circumference of a circle is 22c cm, find its diameter. (π as 22/7).
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.
To find the diameter of a circle, we can use the formula:
Diameter = Circumference / π
Given that the circumference of the circle is 22c cm and π is 22/7, we can substitute these values into the formula:
Diameter = 22c / (22/7)
Simplifying the equation:
Diameter = ((22/7) * 22c) / 22
Diameter = 22c / 1
Therefore, the diameter of the circle is 22c cm.
