In any circle of radius R, how many arcs with lengths R fit into the circumference?

xenn [34]

<h2>~<u>Solution</u> :-</h2>

If we take the radius of a circle be <u>R</u>. Then, we can define that,

$ R = x $

Hence,

Arcs will be as $ 4x $. As,

A circle can be divided into four parts according to the radius.

Hence, we know that,

$x \times 4$

$\mapsto \: 4x$

Hence, <em>according to the radius R</em>, a circle can have <u>4 arcs</u>.
