Answer:
Arc length is equal to
where
is the angle in radians and
is the radius.
Question 1:

So the angle is CFD.
Question 2:

So the angle is AFE.
Question 3:

So the angle is AFB.
Question 4:

So the angle is BFC.
Answer:
-1.6
Step-by-step explanation:
Answer:
B.
Step-by-step explanation:
The best measure of center tendency for this set of data would be the median. It is the best measurement because the data set has an outlier. The outlier is the 30. So to find the median we first order the data set and then find out if the set is an even or odd set. This set is even so we just chose the middle number. If the set was even, we would add the two center number and divide them by 2.
3, 3, 4, 4, 4, 5, 5, 5, 30
The center tendency = 4
Given BD and AC is a diameter of the circle:
We need to find the following:
1. measure of the arc BA
So,
the measure of the minor arc BA = 44
The measure of the major arc BA = 360 - 44 = 316
2. the measure of the arc ACB = 360 - 44 = 316
3. The arc BCD is a semicircle of the circle
So, the measure of the arc BCD = 180
