Question

the ratio of radii of the two circle is 4:5 . find the ratio of their areas. answer in detail

Answer 1

hi buddy thank you for asking this question ,

given that,
ratio=4/5
ratio of area=
$\frac{\pi {4}^{2} }{\pi {5}^{2} }$
(π will be cancelled)
=16/25
hope it's helps !!!
pls give it brainliest and follow me please

Answer 2

Ratio of radii of two circles=r/R
4:5=r/R

Now ratio of their areas will be=πr sq/πRsquare
=r/R
( As π is common and gets cancelled)
=4 square:5 square =16/25(given)

Hope this helps u
