-3 that’s it -3 is the right one
The radius is half the diameter. So the diameter is 14.
1. a = bh/2 2. a = bh/2 3. a = bh/2
=15 x 10 / 2 =24 x 20 / 2 =18 x 32 / 2
= 150 / 2 = 480 / 2 =576 / 2
= 75cm^2 = 240ft^2 = 288ft^2
4. a =12 x 17 /2 5.a=8.5 x 16 / 2 6. a = 15.25 x 18 /2
=204/2 = 136 / 2 = 274.5 / 2
=102in^2 = 68in^2 = 137 1/4 or 137.25in^2
Formula for monthly payment is:
A = P x (r(1+r)^t)/((1+r)^t-1) where P is the amount financed, r is the interest rate divided by 12 and t is the amount of time for the loan in months.
P = 33714 x 0.85 = 28656.90
A = 28656.90 x (0.07/12 (1+0.07/12)^48) / (1 +0.07/12)^48 - 1)
A = $686.23
