First if you want to check your answer take the answer you got and divided it by one of the other numbers like 457*342=156,294 and then dived 156,294 by 342=475 and that's how you know its correct!:) And how you get the answer
The Answer is D. You take 9500 and multiply it by .03.
M= 1/2
to find this you plug in the points into the the formula m=y2-y1 / x2-x1
m=3-6 / -4-2
m=-3 / -6
this simplifies to m=1/2
Base Surface Area = 2π×132<span> = </span><span>1061.8583169134 in2</span>
<span>Lateral Surface Area = 2π×13×14 = </span><span>1143.5397259067 in2</span>
<span>Total Surface Area = </span><span>2205.39804282 in<span>2</span></span>
4 side = 72 ft
2 of the sides = 16 ft
16 x 2 = 32
72 - 32 = 40
40 / 2 = 20
20 ft
