Question

5. The radius of circle O is 24, and OC = 11. The diagram is not drawn to scale.

What is the length of AB? Round the answer to the nearest tenth.
42.7
21.3
52.8
26.4

Answer 1

Answer 2

OB = radius = 24
OC = 11 (from what's given)
AB = 2 * BC

Can you find BC using Pythagoras Theorem?

Answer 3

I think so.

24^2=576
11^2=121
576-121=455
sqrt(455)=21.33
21.33*2=42.66

Answer 4

Nice. :)

Answer 5

Thanks. I didn't think about the Pythagorean Theorem until you said it. :)
