HEY YOU, PLS HELP ME!!!! Determine the arc of AB. Give your answer to two decimal places.
1 answer:
<h3>Answer: 19.48</h3>
========================================================
Explanation:
What you type into that calculator (or any calculator really) is this
(124/360)*2*pi*9
This is because we use this generalized formula
L = (x/360)*2*pi*r
where,
- L = arc length, or distance along the piece of the curve
- x = central angle in degrees
- r = radius
So after typing in that expression, you should get roughly 19.47787445 as shown in the screenshot below.
This then rounds to 19.48
Note: I used the calculator's stored version of pi. If you used something like pi = 3.14, then the answer would be slightly different.
