Question

The diameter of circle X is 15 centimeters. The diameter of circle Y is 20 centimeters.

Which measurement is closest to the difference between the circumference of circle X and the circumference of circle Y in centimeters?

Answer 1

[AI-generated answer — Bot GPT 3.5]

The circumference of a circle is calculated using the formula C = πd, where d is the diameter of the circle.

For circle X:
Circumference of circle X = π * 15 = 47.12 cm

For circle Y:
Circumference of circle Y = π * 20 = 62.83 cm

The difference between the circumference of circle X and circle Y is:
62.83 cm - 47.12 cm = 15.71 cm

Therefore, 15.71 centimeters is closest to the difference between the circumference of circle X and circle Y.
