Problem Statement: Find the radius of a circle whose chord is 10 cm and is at a distance of 12 cm from the centre of the circle.
Solution:
To solve this problem, we will use the following formula:
If a chord of length 'c' is at a distance 'd' from the centre of a circle, then the radius 'r' of the circle is given by:
r = √(d^2 - c^2/4)
Given:
Length of the chord, c = 10 cm
Distance of the chord from the centre of the circle, d = 12 cm
Substituting the values in the formula:
r = √(d^2 - c^2/4)
r = √(12^2 - 10^2/4)
r = √(144 - 25)
r = √119
r = 10.91 cm (approx)
Answer: The radius of the circle is 10.91 cm.
