Answer:
60*pi square inches
Step-by-step explanation:
We have a cone that originally has 15 * pi square inches of area, now it tells us that it is enlarged by a scale factor of four, to make a cone with the same shape.
In other words, if it was a cone with a circular base, this new cone will also be a circular base, the same happens if it is a square base.
Therefore, taking this into account, the new cone area is
15 * 4 * pi = 60 * pi
That is, the area of the new cone would be 60*pi square inches.
The expression that can be used to determine the balance after two years is $500(1.04)².
The balance in the account increases at an exponential rate. Exponential growth is when the rate of growth increases with the passage of time. The formula that can be used to determine the balance after two years is:
- FV = P (1 + r)^n
- FV = Future value
- P = Present value
- R = interest rate
- N = number of years
$500 x (1.04)² = $540.80.
