If that doesn't work, try simplifying the fraction.
6 *20 = 120
8 *60 = 480
120 + 480 = 600 pounds total
Answer:
The midsegment is one-half the length of the base
2.77*10^3+1.04^10^4
2.77*10^3=2770 where (10^3=1000, so 1000*2.77)
1.04*10^4=10400 where (10^4=10000, so 10000*1.04)
2770+10400
=13170
Now, if the diameter is 6 inches, then that means the radius is half that, or 3.
