The formula for the circumference of a circle is:
C = 2πr
Where C is the circumference and r is the radius of the circle.
If the radius of the circle is 2.5 cm, then the circumference can be calculated as:
C = 2π(2.5)
C = 5π
C ≈ 15.71 cm (rounded to the nearest cm)
Therefore, the circumference of the circle is approximately 15.71 cm.
Find the circumference of the circle.
Round your answer to the nearest cm.
