Discussion:
Given: circumference of circle O = 362.14
The circumference of a circle of radius r, is given by the formula C = 2 *PI *2.
So we need to find the value of r in
2*Pi*r = 362.14
Divide both sides by 2*PI to get
r = (362.14)/ (2 * Pi) = (362.14)/ 6.283 (approximately)
= 57.6 (approximately)
Thank you,
