A chord of length 16 cm is at a distance of 6 cm from the centre of a circle. The radius of the circle is— 16 cm 22 cm 8 cm 10 cm
As it forms a right triangle, radius is sqrt(64+35)=10
Chord length is 16.half of it formss base of right angled traingle. Hypotenuse becomes radius Square root of 82 +62=10
