The circumference

Answer :

Given: Diameter of circle = 16.8 cm


To find: The radius of the circle.


Explanation:


Let the radius of the circle be “r” cm.


D=2r cm and Circumference = 2πr cm


According to the given question,


2πr = 2r + 16.8



44 r = 7(2r + 16.8)


44r = 14r + 117.6


44r – 14r = 117.6


30r = 117.6


r = 3.92 cm


Hence the radius is 3.92 cm.
