Answer:
3rd one
Step-by-step explanation:
2l + 2w = P
2w = P - 2l
w = P - 2l / 2
We know that
[length of a circle]=2*pi*r
r=12 in
[length of a circle]=2*pi*12--------------> 24pi in
if 360° (full circle)--------------------> has a length of 24pi in
X-------------------------------------------> 8pi
X=8pi*360/24pi-----------> 120°
the answer is 120°
