Question 13

In reference to a circle the value of $π$ is equal to

(a) $\frac{A r e a}{C i r c u m f e r e n c e}$
(b) $\frac{A r e a}{D i a m e t e r}$
(c) $\frac{C i r c u m f e r e n c e}{D i a m e t e r}$
(d) $\frac{C i r c u m f e r e n c e}{R a d i u s}$

Solution

We know that,
Circumference of a circle $= 2 π r$
Circumference $= π \times D i a m e t e r$ $[∵ d i a m e t e r = 2 r]$
$\Rightarrow π = \frac{C i r c u m f e r e n c e}{D i a m e t e r}$
