Question

a chord of the length 10 cm at a distance of 12 CM from the centre o circle find the radius of the circle​

Answer 1

Answer:

13 cm

Explanation:

(HYPO)^2= (side 1)^2 + (side 2)^2

(x)^2 = (12)^2 + (5)^2

(x)^2 = 144 + 25

(x)^2 = 169

$x= \sqrt 169$

x = 13cm

radius of circle is = 13 cm
