Answer:
A:Joy can use the height of the picnic table to determine the size of the tarp necessary
Answer:
a(n) = 

Step-by-step explanation:
The given expression is in the form of the explicit formula of a geometric sequence.
f(n) = 
Where 'a' = First term of the sequence
r = common ratio
Recursive formula of a geometric sequence is,
a(n) = 
a(n) = 
Where, 
So the recursive formula will be a(n) = 
Circumference = r * 2 * pi
Circumference of track 1 is 376.8
From the little marks on the sides, we can see that YZ is the midpoint segment.
YZ is half of VX
12.2 is the answer.
