We can find this using the formula for arc length (where is the radius of the circle and is the central angle in radians):
In our problem, we are given . This means that:
The measure of the angle is 1.5.
So if the question says at most 30 sq ft than most likely the > is going to go this way even if it has a line that symbolizes equal or more so that kinda narrows it down to 2 and 4. The L is -3ft x 2 Id say 4. Hope I helped
Vertex is
and minimum value of f(x) is 12
Hope this helps
