w^2 = 100 / 49 w = 10/7 or w = -10/7
missing information
We need to know the breaking force and the mass to get the negative acceleration or know the acceleration itself.
physics/math
Ac = v^2/r 1.1 Ac = 2.2 g so Ac = (2.2/1.1)(9.81) = 19.6 m/s^2 v^2 = .169 (19.6) = 3.32 v = 1.82 meters/second that is the speed if you want angular velocity omega = v/r = 1.82 /.169 = 10.8 radians/second
Math
However of course it is not true.

80 = 20 * 5
huh ???
I think the area of the sides (without top and bottom) is A = 2 pi r h (not h^2) A = 2 (3.14) (1.3)(6.2) = 50.6 in^2
Math?
One, ml, is a measure of volume. However grams is a measure of mass. There is no conversion any more than between meters and grams. If you assume some density, such as that of water, then you can do it. For example if water has a density of 10^3 kg/m^3 and a liter is .001 or 1...
math, HELP ME PLEASE!!
Asking customers at a music store if they like music says is not a valid way to find out if "most people" like music. People who do not like to listen to music are not likely to be in the music store.

It said approximate so I used 3.14 for pi
