<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.
The complete question in the attached figure
Let
(2, -R)----------> the point (2, -?)
the equation of a line is
y-y1=m*(x-x1)
point (2.-R) and m=3
so
y+R=3*(x-2)
the answer is the option
<span>y + = 3(x – 2)</span>
