12(pi)
diameter is 4, so radius should be 2
closest height to equal 12(pi) would be 0.96
It is a right triangle
cos 58 = 20/length of rope
length of rope = 20/cos 58 degrees
= 37.74 feet

Answer:
The given expressions simplifies to tan (4x).
Step-by-step explanation:
Here, the given expression is : 
By TRIGONOMETRIC IDENTITY:

Putting this identity here, and taking A = 9 x, B = 5 x, we get

= tan(4x)
Hence, the given expressions simplifies to tan (4x).
