Two circles of same radius 5 cm, intersect each other at A and B. If AB = 8 cm, then the distance between the centre is :
-
- 6 cm
- 8 cm
- 10 cm
- 4 cm
- 6 cm
Correct Option: A
On the basis of question we draw a figure of two circles with centres O and O' , 
Here , AC = 4 cm
OA = 5 cm
OC = √5² - 4² = 3 cm
OƠ = 2OC = 2 × 3 = 6 cm
