OM = 3cm and AB = 8cm. Find the radius of
the circle
​

Answer 1

Answer:

Where is the figure,

first show us the diagram plz.

Answer 2

join A and O

It will be right angle triangle.

OM will be height,AM will be base,AO will be radius of circle and hypotenuse of triangle.

We know

${hypotenuse}^{2} = {base}^{2} + {heigh}^{2}$

${ao}^{2} = {am}^{2} + {om}^{2}$

${ao}^{2} = {4}^{2} + {3}^{2}$

${ao}^{2} = 16 + 9$

${ao}^{2} = 25$

$ao = \sqrt{25}$

$ao = 5$
