Question

In circle O, CD = 44, OM = 20, ON = 19

a. Find the radius. If your answer is not an integer, express it in radical form.
b. Find FN. If your answer is not an integer, express it in radical form.
c. Find EF. Express it as a decimal rounded to the nearest tenth.

Answer 1

Use Pythagoras theorem to find radius OD
OD = OF = OE
use pythagoras to find EN = FN
EN + FN = EF

Answer 2

what is pythagoras?

Answer 3

hyp^2 = side1^2 + side2^2

Answer 4

oh

Answer 5

quick question, does it say or show that Om is perpendicular to CD?

Answer 6
