Answer:

Step-by-step explanation:

slant height = l = 15 mm

radius = r = 7 mm

Surface area of cone = πr (l + r) square units

                                  = 3.14 * 7 *(15 + 7)

                                  = 3.14 * 7 * 22

                                 = 483.56 square mm

1000.00 at 2.5 percent interest for 4 years<br>​
kramer

Answer:

$4100

Step-by-step explanation:

To find the total amount of money, the formula is: principle money × interest rate + 100% × amount of time.

Total amount of money = 1000.00 × \frac{100+2.5}{100} × 4

                                       = 1000.00 × \frac{102.5}{100} × 4

                                       = $4100

If you want to find the interest earned, just deduct the principle amount from the total.
