The sum of the first five terms is 11/2
<h3>How to determine the sum?</h3>
The series is given as:
1/2, -1,2,-4…
Calculate the common ratio of the series using
r = -4/2
Evaluate
r = -2
The sum is then calculated as:

This gives

Evaluate

Evaluate

Hence, the sum of the first five terms is 11/2

Answer:
30 inches
Step-by-step explanation:
The circumference of a circle can be found by using 2
r, or
* d.
Since we are given the circumference of the circle, 30
, you can find the diameter by solving for the diameter (after substituting in the circumference) in the formula for circumference.

To cancel out
you can divide both sides of the equation by pi. Now you have:
30 = d
Therefore the diameter of the circle is 30 inches.
