Help me with number 2 I need help fast with the right answer with showing work

Volume of a cylinder is defined as:

v = volume

r = radius

h = height.

V = (r^2)h

In this problem,

v = 1,356.48 in^3

r = 6 in

h = ?

Plug our numbers into the volume formula above.

1,356.48 in^3 = (6^2)h

Divide both sides by (6^2) to isolate variable h

12.0 = h

The height of the cylinder is 12.0 inches

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.

if you could provide answer choices that might allow me to answer the question easier if my above answer isn't an option! (:

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
