Arc length has a formula that is similar to arc measure, but arc length is expressed in inches or meters or miles, etc., whereas measure is expressed in degrees, like an angle.  The formula for each take this into account.  Since the arc length is part of the length of the outside of the circle, the formula includes the circumference for a circle.  AL= \frac{ \theta }{360} * \pi d, where theta is the degree measure of the central angle intersecting the arc you're looking for, and d is the diameter of the circle.  Our formula would look like this with the info we have: AL= \frac{30}{360}* 24 \pi which can be simplified to AL= \frac{1}{12}*24 \pi which can be simplified even further to AL=2 \pi.  And that's your answer!

<h3>What is Frequency?</h3><h3>Frequency refers to the number of times an event or a value occurs. A frequency table is a table that lists items and shows the number of times the items occur.</h3>

Here, in given data about the six concerts

Concerts              Frequency

Answer:

D

Step-by-step explanation:

1/4 (84x - 100)=?<br><br>I can't solve it! please help me!
slamgirl [31]
The answer is 21x-25 because all you have to do is multiply the 1/4 by the 84x and then multiply 1//4 by negative 100. A simpler way of explaining this is just that you need to distribute
