Question

The circumference of a circle exceeds the diameter diameter by 16.8cm find the circumference

Answer 1

Answer:

24.64 cm

Step-by-step explanation:

Let d be the diameter and r be the radius

Circumference of Circle = 2πr = πd. ( ∵ d= 2r)

Given Circumference exceeds diameter by 16.8 cm

Circumference of circle - Diameter of circle = 16.8

=> πd - d = 16.8

=> d(π - 1) = 16.8

=> d (22/7 - 1) = 16.8  (∵ π = 22/7)

=> d = 16.8 *7/15 = 7.84 cm.

Circumference of Circle = πd = 22/7 * 7.84 = 24.64 cm.
