If the sum of the circumferences of two ...

If the sum of the circumferences of two circles with radii `R_(1)` and `R_(2)` is equal to the circumference of a circle of radius R, then

A

`R_(1) + R_(2) = R`

B

`R_(1) + R_(2) gt R`

C

`R_(1) +R_(2) lt R`

D

Nothing definite can be said about the relation among `R_(1), R_(2)` and R.

Text Solution

Verified by Experts

The correct Answer is:
A
According to the given condition,
Circumference of circle = Circumference of first circle + Circumference of second circle
`:. 2piR= 2piR_(1)+ piR_(2)`
`rArr R = R_(1) + R_(2)`
