A 1 and 1/2 oz. bottle of roll-on deodorant has a height of 4 in. and a radius of 3/4 inches. Find the surface area of the bottle if the bottle is shaped like a silo. Use 3.14 for π.
Altitude of a launched object. The altitude of an object, in meters, is given by the polynomial
h + vt − 4.9t2,
where h is the height, in meters, at which the launch occurs, v is the initial upward speed (or velocity), in meters per second, and t is the number of seconds for which the object is airborne

dumbcow · Answer

by "silo" do you mean cylinder?

anonymous · Answer

yes

anonymous · Answer

it was all in one paragraph, it might be 2 problems in 1 ... not sure

dumbcow · Answer

here is equation for surface area of cylinder
$$SA = 2\pi r^{2} + 2\pi r h$$
