Question

the length of a chord of circle of radius 10 cm is 12 cm find the distance of the chord from the centre. pls answer this question ​

Answer 1

Answer:

8 cm

Step-by-step explanation:

The chord and the two radii forms an isosceles triangle.

Find the area of the triangle:

s = ( 10 + 10 + 12) ÷ 2 = 16 cm

area = √16(16 - 10)(16-10)(16-12)

area = 48 cm²

Find the height of the triangle:

area = 1/2 x base x height

1/2 x 12 x height = 48

6 x height = 48

height = 48 ÷ 6 = 8 cm

Answer: The height is 8 cm
