Answer 2

Answer:

Before I begin, round the answer to the smallest value. Anyways, here's how I solved it:

To find the area, we must take the diameter, which in this case is 2.5, and divide it in two to find the radius:

2.5/2 = 1.25

Remember, the AREA of ANY circle is r^2 x 3.14 (pi). So, plugging in the equation with all the info we know:

1.25^2 = 1.5625 x 3.14 = 4.90625

Now, we need to find the cost, which we will do in this equation:

4.90625 x 32.50 (finding the total for each repetition) = 159.453125

So, the total cost is $159.45.
