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 3.14159, and d is the diameter of the circle. Given a diameter of 65 cm, the circumference would be C = π(65) = 65π cm, which is approximately 204.203 cm.

JudyAh, what a lovely question! To find the circumference of a circle, you can use the formula C = πd, where d is the diameter. So, for a circle with a diameter of 65 cm, the circumference would be 65π cm, or approximately 204.2 cm. Just imagine that beautiful circle, perfectly round and full of possibilities!
Assuming you are talking about a circle, you simply multiply the diameter by pi. Keep the result (in this case) as 65pi to have it exact, or use an approximation of pi such as 3.1416, and do the multiplication, if you want an actual number.
