Question

. A circle with center O has a chord AB and its distance from center

is 8 cm and length of chord is 12 cm. Find the radius of the circle.​

Answer 1

Answer:

10cm

Step-by-step explanation:

draw a circle with centre O and a chord AB . draw a perpendicular OC on AB from the centre of circle. now join OA

now in triangle∆ AOC

OC=8cm

AC=1/2AB

AC=1/2×12

AC=6cm

by Pythagoras theorem

AO²=OC²+AC²

AO²=8²+6²

AO²=64+36

AO²=100

AO=√100

AO=10cm

thus, radius of circle is 10cm
