11-5=6
18-11-7
26-18=8
........... so on and so forth.
I think you get the point.
6 divided by 2 and 1 forths is going to be 8 out of 3
6 / (x+1) = 1/2
x +1 = 12
x = 11
Answer is d ....(11)
If x is 0 then I think it would be the 3 to the second power and that is 9. Because 0 + 9 = 9. Correct me if I’m wrong!
The volume of a cone is 1/3 pi r^2 h. So by substitution, V = 1/3 of 80pi which simplifies to V=26.667pi, which when multiplied out, provides the answer V = 83.8 cubic meters.
