Question

HEY YOU, PLS HELP ME!!!! Determine the arc of AB. Give your answer to two decimal places.

Answer 1

Answer:  19.48

========================================================

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.
