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
