If the sum of circumferences of two circles wirh radii r1 & r2 is equal to the circumference of a circle of radius r, then what is true
1 r1+ r2 = r or sum of their squares= r2
Answered by Reiny
"sum of circumferences of two circles wirh radii r1 & r2"
= 2πr1 + 2πr2
"the circumference of a circle of radius r"
= 2πr

they are equal ....

2πr1 + 2πr2 = 2πr
2π(r1 + r2) = 2πr
divide both sides by 2π
