Two circles touch each other externally The distance between their centres is 14 cm and the sum of their areas

let the radius of 1st circle be xcm.
and the radius of 2nd one is (14-x)cm.
so,
(pi*x*x)+(pi*(14-x)*(14-x))=130
from here we can find the value of x.

@ krishna mahato how u are solving by taking the area as 130pi wen d area is 130 cm^2

Question wrong....

two circles touch externally the sum of their areas is 130pi cm2 and the distance between their centres is 14cm find the sum of their radii

let d radius of 1 circle = x
other one = 14-x
now apply the formula and put the value get the ans

radius of each circle is 7 cm. as both of the circles touches each other externally so the distance of their centres will act sa diameter and thus radii will be 7 cm.

wrong question
as R^2 + r^2 = 130/pi = (130/22)*7 = 41.37 ...................i
and R + r = 14...................................................................ii
how i and ii are possible while
1^2 + 11^2 = 122
2^2 + 10^2 = 104

Two circles touch each other externally. The distance between their centres is 14 cm and the sum of their areas is 130 cm2. Find their radii.
