Answer:
44 cm
Step-by-step explanation:
The circumference formula is:
C = 2πr
We are given the circumference of circle O, so we substitute C with the given circumference and solve for r.
88π cm = 2πr
Switch sides:
2πr = 88π cm
Divide both sides by 2π:
r = 44 cm
The answer is choice B: 22.52 units.
We use the Pythagoras's theorem which says for a right triangle with sides and hypotenuse :
In our case
So we solve for
Which is choice B.
