Question

If r=2 units what will be ratio of it's perimeter and π

Answer 1

Answer:

$Ratio \:of \:perimeter \:and \:\pi = 4:1$

Step-by-step explanation:

Radius (r) = 2 units

$ratio =\frac{perimeter}{\pi}\\=\frac{2\pi r}{\pi }\\=2r\\=2\times 2\\=4$

Therefore,

$Ratio \:of \:perimeter \:and \:\pi = 4:1$

Answer 2

$\huge\sf{Answer:-}$

Let R be the radius.

Hence,

R = 2 units

$\sf R = \frac{perimeter}{\pi} \\ \sf = \frac{2 \pi \: R}{\pi} \\ \sf = 2R \\ \sf =( 2 \times 2) \\ \sf = 4$

Hence, 4 : 4 is the ratio of it's perimeter and π
