Question

Circumference of a circle exceeds by 16.8 cm Find the radius of a circle

Answer 1

Answer:

ANSWER

Given,

 That the circumference of a circle exceeds its diameter by 16.8cm .

⇒2πr−2r=16.8

⇒2r(π−1)=16.8

⇒2r(722−1)=16.8

⇒2r=1516.8×7

⇒r=3016.8×7=300168×7=3.92cm.

Hence, circumference of circle is 3.92cm
