Question 4
If the sum of the circumferences of two circles with radii R1
and R2 is equal to the circumference of a circle of radius R, then
R1 + R2 = R
(B) R1 + R2 > R
(C) R1 + R2 < R
(D) Nothing definite can be said about the relation among R1 , R2
and R.
Given that
sum of the circumferences of two circles with radii R1 and R2 is equal to the circumference of a circle of radius R
Therefore,
2𝜋𝑅_1+2𝜋𝑅_2= 2𝜋𝑅
𝑹_𝟏+𝑹_𝟐=𝑹
So, the correct answer is (A)
