Question

if the length of the chord is 2cm and distance from the centre is 1cm then find the radius of circle​

Answer 1

Explanation:

Let r be the radius of the circle

r^2=1^2+(6/2)^2=10

r=(10)^1/2

Let the length of the cord which is 2cm away be p cm.

r^2=2^2+(p/2)^2

10=4+(p/2)^2

6^1/2=p/2

p=2(6)^1/2

Answer 2

Answer:

radius of the circle is √2cm
