Answer:
Diameter of Circle = 8 cm
Step-by-step explanation:
We Have :-
Circumference exceeds its diameter by 16.8 cm
To Find :-
Diameter of the circle
Formula Used :-
Circumference of Circle = 2πr
Diameter of Circle = 2r
Solution :-
2πr = d + 16.8
2πr = 2r + 16.8
πr = r + 8.4
πr - r = 8.4
r ( π - 1 ) = 8.4
2.14 r = 8.4
r = 8.4 / 2.14
r ≅ 4 cm
Diameter = 2r
= 2 * 4
= 8 cm
Diameter of circle = 8 cm
