Question 14

Circumference of a circle is always

(a) more than three times of its diameter
(b) three times of its diameter
(c) less than three times of its diameter
(d) three times of its radius

Answer 1

We know that,
Circumference of a circle $=2\pi r$
$\therefore Circumference=2\times 3.14\times r$ $[\because \pi =3.14]$
$\Rightarrow$ Circumference =$3.14\times d$ $[\because d=2r]$
So, circumference of circle is always more than three times of its diameter
