Answer :

Given : The circumference of a circle exceeds the diameter by 16.8 cm.
To find : The circumference of the circle.
Solution :

Let diameter of circle = X cm

So, acc. to given condition

Circumference = x+16.8 cm

Circumference of circle is 2πr.

⇒2πr = x + 16.8
Diameter = 2r

⇒ 15 x=16.8 × 7
⇒15 x=117.6

Circumference= x + 16.8 (x = 2r)

Circumference=7.84 + 16.8 = 24.64 cm
