Perimeter =add up all sides.
Perimeter = 5+1+5+9
=20 units
I think it is..................
First keep in mind that the given value is negative and that it is
greater than or
equal to whatever '<em>v</em>' is.

When solving for a variable in any equation, you do something to both sides in order to keep it equal. Here, <em>v</em> is being subtracted by 1.9; therefore we can
add 1.9 to both sides in order to isolate <em />the variable.


Despite not needing a value for the question, it is worth noting that since this is an inequality, <em>v </em>can be any value from -6.4 to ∞ in order to make it true.
Answer:
207.24 inches
Hope this helps
Step-by-step explanation:
first you need to find the circumference...
2pi R (r=radius=11)
2 x 3.14 x 11 = 69.08 (i'm using 3.14 as pi so yea...)
3 rotations...
69.08 x 3= 207.24 inches
