Answer 2

QUESTION :

Circle with centres A, B and C touch each other externally. If AB=3

cm, BC=3 cm and CA=4 cm, find the radii of each circle.

3 marks

ANSWER :

=> AB = R1+R2 = 3 cm

BC = R2+R3= 3 cm

CA= R3+R1 = 4 cm

AB+BC+CA = 2(R1+R2+R3)= 3+3+4= 10

R1 + R2 + R3 = 5

R1 + R2 + R3 = 5

r1+3=5

r1 = 5-3=2 cm

r1 +4= 5

r1 = 5-4= 1 cm

r3+3= 5

r3= 5-3 = 2cm

=> ANS - R1 = 2 cm , R2 = 1 cm, R3 = 2 cm
