The general vertex form equation of the parabola is

The Axis of Symmetry is given by
x=h
For the given equation the Equation of the Axis of symmetry for the parabola y=1/2(x-3)^2+5 as x=3.
I believe it's 9.1 Hope this helps :)
Volume of a Cylinder = πr²h
V = π * (11)² * 15
v = π * 121 * 15
v = 1815π units³
In short, Your Answer would be Option C
Hope this helps!
39° or B that should be it
Maybe c or A not completely sure try looking for the one you think it is and try reading it again
