61-34x98+90+21-4
We will put these in parenthesis to make it easier to read, and to mark what needs done first.
61-(34x98)+90+21-4
34x98=3,332
Now that the multiplication is done, we add and subtract.
90+21=111
61-3,332=-3271
-3271+111-4
We can reorder this to make it easier. Plus, we'll subtract -4 and -3271.
111-3275=-3164

sorry if this doesn't help
Volume = base area * height. Base area = πr^2 = 1/4 * π (diameter)^2 = 9π.
Height = volume / base area = 9.6.
The final correct answer
(2.2, -1.35) and (2.2, -1.4)
Your welcome!
Also, could I be marked brainliest?
