Q4 of 68 Page 16

The circumference of a circle exceeds the diameter by 16.8cm. Find the circumference of the circle.


Let diameter of circle = X cm


So,


Circumference = x+16.8cm


2πr = x + 16.8 (Diameter = 2r)


= x + 16.8 (x = 2r)


= 16.8


= 16.8


= 7.84 cm


Circumference = x + 16.8


= 7.84 + 16.8 = 24.64 cm
