A = (pi * r^2)/2
A = (3.1416 * (14.3/2)^2)/2
A = 80.3 ft^2
In item# 1, we are only given with the height of the tree a=15 meters and we are asked to solve for the hypotenuse. Since we are not given with angle created between the rope the ground level we will assign it as ∠A = ∅
Solving for the length of the rope, we have
sin A = 15/Length of rope
Length of rope = 15 meters / sin A
In item#2, assuming that it is a right triangle we have:
8 ²= x²+3.5²
x=7.2
The smallest angle:
sin Z =3.5/8
Z = 25.95°

Answer:
It is reflection
Step-by-step explanation:
We know these three rules:
-a rotation followed by a rotation is a rotation
-a reflection followed by a reflection is also a rotation
-a rotation folowed by a reflection is a reflection
So we have: f3r3 is f (reflection)
f2 f is r (reflection)
r3 r is r
f2 r is f
r2 f is f
r1 f is f
So, r1r2f1r3f2f3r3 is reflection.
