Question

The radii of the circles with centres O
and P are 10 cm and 17 cm respectively.
If OP = 5 cm, how many common
tangents do these circles have ?​

Answer 1

Answer:

0

Step-by-step explanation:

let r1 and r2 be the radius and d be the distance between two centres.

r1=17 CM and r2=10 CM and d=5 CM.

d<r1-r2 then there are no common tangents.

5<17-10

5<7

Hence, no common tangents are there for given circle.
