Answer:
Hence r=10.3 cms (rounded to tenth place)
Step-by-step explanation:
In Triangle KLN ,
KN = 5 Cms
LN = ½ of LM
As the Perpendicular dropped from the center to the chord bisects it.
LM = 18 cm
LN = 9 cm
Now we have to find r or KL
We apply Hypotenuse Formula in this
The formula is given as
[tex]c=\sqrt{a^2+b^2}[/tex]
Where c = r
a=5
b=9
Putting them in the formula
[tex]r=\sqrt{5^2+9^2}[/tex]
[tex]r=\sqrt{25+81}[/tex]
[tex]r=\sqrt{106}[/tex]
[tex]r=10.29[/tex]
