Question

the radius of a circle is 10cm and the length of a chord is 12cm. Then, calculate, the distance between the chord and centre of the circle.​

Answer 1

Answer:

Distance between chord and radius is 8 cm

Step-by-step explanation:

let's draw one circle with radius 10 cm. If the length of chord is 12cm them divide a chord in re equal parts I.e 12/2=6cm. Therefore now draw one line joining the center of chord and the point of radius which attached on the circle. Therefore now a right angle triangle form. By using Pythagoras theorem 10^2=6^2+ (distance between chord and radius )^2

Therefore 100-36= (distance between chord and radius )^2

Therefore (distance between chord and radius)^2=64

Distance between chord and radius =8

Hence we get distance between chord and radius is 8cm
