Answer :

To find the circumference of a circle when given the diameter, you can use the formula: Circumference = π * diameter Given that the diameter is 7cm and π = 22/7, you can substitute these values into the formula: Circumference = (22/7) * 7 Simplify the expression by canceling out the common factor of 7: Circumference = 22 Therefore, the circumference of the circle is 22 cm.
