R^2π=500in^2
r^2=500 in^2/π
r=(500 in^2/π)^(1/2)= 12.62 in
plug it in:
db=3da=3(2(12.62))= 75.69
r of b = 75.69/2=37.85in
A of b = (37.85in)^2π = 8.22 in^2

Hi. This is is how it goes tep by step.



Cut the rectangle/shape the way you feel more comfortable. However, you don't know so I will recommend you cut it in half from where the 12 is. so now the 12 ft would be broken in to 2. the top section would be 45 ft because 5 times 9 is 45. the bottom would be 98 because 7 time 14 is 98. the total would be 143. for the first one.

Jamie purchased a condo in Naples, Florida, for $699,000. She put 20% down and financed the rest at
ololo11 [35]

By applying the formulas of present and future values of annuity we can solve this problem. In this mortgage problem, first we have to find loan amount after the down payment. It is 699,000 - 699,000 * 0.2 = 559,200$. We have to set it as PV (Present Value) of annuity. Using the PV formula PV = A \frac{[1- \frac{1}{(1+r)^{N}}]}{r}, we first find A, which is an annual payment. Exact calculation with mortgage calculator gives us A = 33,866.56$. After finding it, plugging this number into FV (Future Value) formula FV = A\frac{[(1+r)^{N}-1]}{r}, we find the value of the future value and it is 1,185,329.66$. And the total financial charge is 1,185,329.66 - 559,200 = 626,129.66$
