Step-by-step explanation: 12,000 x 4 = 48,000
48,000 + 198,000 = 246,000
Ans: x=1.590667 or x= -1.257334
2.75 as a mixed number would be:
side one is 5 side two is 10 and the third side is 13. 28 is not divisible by three so if one side i 5 ft longer and another side is 8 ft longer then you add them 5+8=13 then subtract 13 from the perimeter 28-13=15 then divide 15 by 3 and get 5 5 5. add 5 (5+5) (5+8).
Volume of a cone = (1/3) x Area of the base (B) x height(h)
V = (1/3)·420·180
= 25200 mm³
