Answer:

1. 18.84 2. 172.2 3.219.8

Step-by-step explanation:

1.   formula: v=(r*pi)*h

v=(6^2*3.14)*4

v=(36*3.14)*4

v=113.04*4

v=452.16

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=(5^2*3.14)*11

v=(25*3.14)*11

v=78.5*11

v=863.5

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

v=(7^2*3.14)*10

v=(49*3.14)*10

v=153.86*10

v=153.86
