A silo is being built in the shape of a cylinder with a hemisphere roof. If the radius is 3.0 m and the height is 5 m, determine the amount of material needed for the sides
and roof. Round your answer to the nearest tenth of a square m. Do not put units in
your answer and use pi=3.1416 or the pi button on your calculator.

step-by-step explan mxfcg'k; uafwgzfgjhklhgation:

the answer is d

step-by-step explanation:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
