Question

The ratio of circumference to diameter of any circle is equal to

• A. 3.141
• B. 7.545
• C. 3.414
• D. 7.454

Answer 1

The correct option is A 3.141

We know that diameter of a circle is twice its radius, i.e., d = 2r.
$\therefore$ Circumference, C = $2\pi r=\pi d$
$\Rightarrow \frac{Circumference}{Diameter}=\pi =3.141$
