Find the circumference of a circle whose diameter is 10 cm
The formula for the circumference of a circle is C = πd, where d is the diameter of the circle and π is a mathematical constant approximately equal to 3.14.
Given that the diameter of the circle is 10 cm, we can substitute this value into the formula to find the circumference:
C = πd
C = π(10 cm)
C = 31.4 cm
Therefore, the circumference of the circle is 31.4 cm.
