Question

if the ratio of the radii of two circle is 2 ratio 3 find the ratio of their areas ​

Answer 1

Answer :

Your answer is => 4:9

Step-by-step explanation:

Ratio of radii two circles = 2:3

So, radius of first circle = 2x ------ (r)

and, radius of second circle = 3x ------ (R)

Therefore,

Required Ratio

$= \frac{area \: of \: first \: circle}{area \: of \: second \: circle} \\ \\ = \frac{\pi {r}^{2} }{\pi {R}^{2} } \: \\ \\ = \frac{ {(2x)}^{2} }{ {(3x)}^{2} } \\ \\ = \frac{ {4x}^{2} }{ {9x}^{2} } \\ \\ = \frac{4}{9} \\ \\ = 4:9$

Therefore the required Ratio is 4:9
