Answer:
15 Cm
Step-by-step explanation:
Given:
Length of Chord=24 Cm
Distance from the center=9 Cm
Cons. :
Join the center point to the One end of the chord
Draw A Line Perpendicular to the chord to the center of circle
Sol:
H^2+B^2=Hy^2
B= Half of the chord because a perpendicular to Center Divides it into half
Hy= the radius of the circle
=>9^2+12^2=Hy^2
=>81+144=(radius)^2
=>225=(radius)^2
radius=15 Cm
^ means in this equation
Power
^2 means Square of the value
means
^2 = Square of the value in front of it
