PLEASE HELPPP I only have a bit of time for this :(

1. 18.84 2. 172.2 3.219.8

Step-by-step explanation:

1.   formula: v=(r*pi)*h

v=6*3.14*4

v=18.84

2. formula: v=(r*pi)*h

because you were given the diameter for number 2 you would have to do 10/2 to find the radius. so 5

now plug it into you're equation.

v=5*3.14*11

v=172.7

3. formula: v=(r*pi)*h

v=7*3.14*10

v=219.8

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
