The circumference of a circle can be calculated using the formula C = πd, where C is the circumference, π is a constant (approximately equal to 3.14), and d is the diameter of the circle.
Given that the diameter is 20 inches, we can substitute this value into the formula to find the circumference:
C = πd
C = 3.14 * 20
C = 62.8 inches
Therefore, the circumference of the circle is 62.8 inches.
Find the Circumference of the circle if the diameter is 20in. Use 3.14 for pi.
