The diameter of circle X is 15 centimeters. The diameter is 20 centimeters. Which measurement is the closest to the difference between the circumference of circle X and the circumference of circle Y in centimeters
The circumference of a circle is calculated using the formula C = πd, where d is the diameter of the circle.
For circle X:
Circumference = π * 15 = 47.12 cm (approximately)
For circle Y:
Circumference = π * 20 = 62.83 cm (approximately)
The closest measurement to the difference between the circumferences of the two circles is 63 - 47 = 16 cm.
