Question

find the radii whose area is 22/7cm²​

Answer 1

Step-by-step explanation:

Area is

$\pi \: r {}^{2}$

so 22/7=22/7 r^2

R

$r {}^{2} = 1$

Then r=1 cm

So the radius of circle is 1cm

Answer 2

Answer:

Given: Area of circle=22/7cm²

let the radius of circle be r

so, area of circle=πr²

=22/7=22/7*r*r

=r²=1

r=1

ans. radius of circle is 1cm

please mark my answer as brilliant it will help.
