surface area of prisms. please help with the work shown because i can't figure out how to solve these :(
8090 [49]

here: :)

I did the work, and basically i solved for the area of the faces and then multiplied that by two to get the total surface area of the faces. Then I added in the areas of the sides connecting the two faces:

just as a referral: the formulas to find the faces are as follows:

rectangle: length times width

circle: pi x r^2

trapezoid: h(base1 + base2)

and triangle: (b x h)/2

Kyle has a loan of $32,890
Anuta_ua [19.1K]

Answer:

$2,631.20

Step-by-step explanation:

We are told that the loan has a simple interest rate of 8% per year. This means that every year that goes on without Kyle paying back the money, he will have to pay an extra 8% of $32,890 as interest.

After one year, he only has to pay back one lot of interest, just 8% of $32,890.

To find that number we can change 8% into a decimal: 8%/100% = 0.08

And then multiply this by the amount of loan money:

0.08 x 32,890 = 2,631.20

Kyle has to pay $2,631.20 of interest at the end of one year.

Hope this helped!
