Question

If two equal circles with centres A and B are
intersecting at P and Q. If AB = 6cm
and PQ = 8cm , find their radii.​

Answer 1

Answer:

5cm

Step-by-step explanation:

Given

AB=6cm

PQ=8cm

OP=OQ=4cm

from triangle AOP

AP square=OP square+OA square

r1 square= 4 square+3 square

r1 square= 16+9

r1 square=25

r1=Root over 2

r1=5 cm

Therefore r1=r2

r2=5cm
