Question

Find the radius of circle if AB = 24 and OC = 5

Answer 1

13

Explanation:

Since OCB forms a right triangle, you can find the length of side OB and therefore the radius by simply using the pythagorean theorem. The first step is to note that, since AB=24 and OC bisects that, that both CB and AC have length 12. Therefore, the radius is
`BO=√(12^2+5^2)=13`. Hope this helps!
