Question

distance between their centres is 12 cm, in how many points do the circles intersect
11 sin A=
2
15. If the radii of two circles with centres O and O' are 7 cm and 10 cm and
4+1
rides of length 120​

Answer 1

Answer:

At 2 points

Step-by-step explanation:

Distance between their centres is 12 cm

The radii of two circles with centres O and O' are 7 cm and 10 cm

As the centres are separated by a distance of 12 cm, they will intersect at 2 points.

NOTE:

If the distance between their centres was 17 (7+10) cm, they would have just 1 point of contact.

If the distance between their centres was greater than 17 (7+10) cm, they would have no point of contact.
