Question

two circles touch each other internally then between their centres is 5cm, if they touch externally then the distance between their centres is 25. Find the radii of the circles.​

Answer 1

Answer:

Answer. Answer: Distance between their centres is 25 cm or 5 cm . By theorem of touching circles, the centres and point of contact are collinear

Answer 2

Step-by-step explanation:

Let a be the radiud of the first circle

and b be the radius of the second

so, when the two touch internally,

a-b= 5(I)

and when they touch externally,

a+b=25(ii)

so solving the two we get

a=15 and b=10
