We know that
circumference=2*pi*r
for r=3 in
circumference=2*pi*3------> 18.84 in
if 2*pi radians (full circle) has a length of--------> 18.84 in
7*pi/3 radians-----------------> x
x=7*pi/3*18.84/(2*pi)-------> x=21.98 in
the answer is
21.98 in

Step-by-step explanation:
<u>Given</u>:
A conveyor belt carries bales of hay from the ground to the loft of a barn 27 feet above ground.
The belt makes an 30° angle with the ground.
We need to determine the distance that the bale of hay travel on the conveyor belt.
<u>Distance that the bale of hay travel on the conveyor belt:</u>
The distance that the bale of hay travel on the conveyor belt can be determined using the trigonometric ratio.
Let the distance that the bale of hay travel on the conveyor belt be x.
Thus, we have;
Substituting and
Thus, we get;
Simplifying, we get;
Thus, the value of x is 54 feet.
Hence, the distance that the bale of hay travel on the conveyor belt is 54 feet.
