1.	15. If the radil of two circles with centres O and O' are 7 cm and 10 cm and thedistance between their centres is 12 cm, in how many points do the circles Intersect?
Answer» Answer: Let radii R1=7cm and R2=10cm are the radius of O centred CIRCLE and O'centred circle. given, OO'= 12cm. and R1+R2=17cm. It MEANS, circles are intersect each other at two DIFFERENT. As SHOWN in the FIGURE above

given, OO'= 12cm.

and R1+R2=17cm.

It MEANS, circles are intersect each other at two DIFFERENT.
