Question

HURRY WILL MAKE BRAINLEST!! circle F is shown below. EB is a diameter and the radius is 3 units. Choose the correct

Answer 1

Answer:

Arc length is equal to $\theta r$ where $\theta$ is the angle in radians and $r$ is the radius.

Question 1:

$\frac{\pi}{2}=\frac{\pi}{6}\times3$

So the angle is CFD.

Question 2:

$\pi=\frac{\pi}{3}\times3$

So the angle is AFE.

Question 3:

$2\pi=\frac{2\pi}{3}\times3$

So the angle is AFB.

Question 4:

$\frac{3\pi}{4}=\frac{\pi}{4}\times3$

So the angle is BFC.
