If ABC is a quarter circl
e and a smaller circle is inscribed in it; if radius of quarter circle is 1.414units. Find the radius of smaller circle
Read Solution (Total 6)
-
- if r be radius of smaller circle then
distance b/n centres = √2 * r
so, r + r√2 = R here,R = 1.414 =√2
=> r=(√2 -1)R
r = 0 .586 unit - 9 years agoHelpfull: Yes(25) No(7)
- how the distance between the centres become sqrt(2).r...............?

- The distance of the center comes as the tangnt to the cirlce always make 90 deg so from hypt thrm 2pow1/2 +2pow1/2= 2*2pow1/2 how it is come

- distance btw center of small circle (r) and big circle (R)=R*r
=√2 * r
