Answer:

3,992.34 (I think)

Step-by-step explanation:

Set an equation:

25000(1+.025)^6

and you should get an answer of 28992.33546

Then you should subtract the initial amount which is 25000 to find out how much interest is being paid.

So finally the answer would be 3,992.34.

Step-by-step explanation:

To solve question 4, you have to work backwards. Plug 40.82 as C in the formula C = D x 3.14. It would now look like: 40.82 = D x 3.14. Divide 40.82 by 3.14 and you would receive 13 as the diameter. However, we are searching for the radius. The radius is half of the diameter. 13 / 2 is 6.5

To solve question 5, you'll need to use the formula C = D x 3.14. So far, we know D is 6. 6 x 3.14 is 18.84. Yet, we need to find the cost. Each foot costs $12.50, so that's what we multiply to 18.84. In the end, the cost is $235.50.
