Question

The length of a chord which is at a distance of 4 cm from the center of a circle is 6 cm,find the diameter of circle

Answer 1

Answer:  6 cm

Step-by-step explanation

Length of chord = 6 cm

because diameter is also a chord so diameter = 6 cm

Answer 2

Answer:

so in that case we'll have a right angled triangle with perpendicular = 4 cm

base = 3 cm

and hypotenuse = r ( radius of circle)

by pythagoras theorem

r = √( 4^(2) + 3^(2) )

r = √(25)

r = 5 cm

so diameter is 10 cm
