Webb7 maj 2024 · Best answer Let O be the centre of the concentric circle of radii 4 cm and 3 cm respectively. Let AB be a chord of the larger circle touching the smaller circle at P. Then AP = PB and OP ⊥ AB Applying Pythagoras theorem in OPA, we have OA2 = OP2 + AP2 ⇒ 16 = 9 + AP2 ⇒ AP2 = 7 ⇒ AP = √7 cm ∴ AB = 2AP = 2√7 cm +2 votes WebbIt is given that two circle having radii 3.5 cm and 4.8 cm touch each other internally. We know, the distance between the centres of the circles touching internally is equal to the difference of their radii. ∴ Distance between the centres of the two circles = 4.8 cm − 3.5 cm = 1.3 cm. Thus, the distance between their centres is 1.3 cm. imber avenue amesbury imbera refrigeration mexico
