This symbol means that you have to evaluate the generic term at n=1,2,3,4,5, and then sum all the terms. Here's the table:
So, their sum is
Alternatively, you manipulate the expression to get
For the first sum you can use the formula
The second sum is simply 1 summed 5 times with itself: 1+1+1+1+1=5.
So, we have
Answer:
B, of the two choices I see, would be the right equation.
And z = 15
Step-by-step explanation:

Circumference,C = 2 πr
C= 2 x 3.14 x 3
C= 18.84 inches
