  • R = 28/2 - 2 = 12 in
  • r = 6/2 = 3 in

<u>Find the area:</u>

  • A = π/8(12² - 3² ≈ 53 in²

<u>Outer perimeter of the frame:</u>

  • P = d + πd/2 =28( 1 + π/2) ≈ 72 in

MissTica
The future value of a monthly deposit A=125.30 at annual interest i=0.015 per annum for n=35 years compounded monthly is given by
FV=A((1+i/12)^(12*n)-1)/(i/12)
=125.30(1+0.015/12)^(12*35)/(0.015/12)
=$69156.05

The annuity formula is given by
Payment = r(PV)/(1-(1+r)^(-n))
where
r=interest rate per period = 0.015/12
PV= $69156.05
n=20*12=240
so
Payment = (0.015/12)<span>69156.05/(1-(1+0.015/12)^(-240))
= $333.71  per month.</span>
