Answer 2

Calculation of the Circumference of a Circle

To find the circumference of a circle, we can use the formula C = πd, where C represents the circumference and d represents the diameter of the circle.

In this case, the diameter is given as 25 cm. To calculate the circumference, we can substitute the value of the diameter into the formula:

C = π * 25

To find the value of π, we can round it to the nearest tenth, which is 3.1 Substituting this value into the formula, we get:

C = 3.1 * 25

Calculating this, we find that the circumference of the circle is:

C = 77.5 cm

Therefore, the length of the circumference of the circle with a diameter of 25 cm is 77.5 cm.

I hope this helps! Let me know if you have any further questions.
