Cylinder:
V = pi * r^2 * h
V = 3.14 * 9^2 * 11
Simplify exponent:
V = 3.14 * 81 * 11
Multiply:
V = 2797.74
Sphere:
V = 4/3 * pi * r^3
V = 4/3 * 3.14 * 9^3
Simplify exponent:
V = 4/3 * 3.14 * 729
Multiply:
V = 3052.08
Cone:
V = 1/3 * pi * r^2 * h
V = 1/3 * 3.14 * 12^2 * 20
Simplify exponent:
V = 1/3 * 3.14 * 144 * 20
Multiply:
V = 3014.4
So the Sphere holds the most.
Answer:
Cost to paint 4 walls of a room = $24.20
Cost of painting 3 walls of a room =$18.15
Step-by-step explanation:
(a) Abby purchased 4 2/5 gallons of paint to paint 4 walls of a room in her house.

1 gallon cost = 5.50
So 22/5 gallons cost = 
Cost to paint 4 walls of a room = $24.20
(b)cost of painting 4 walls of a room = $24.20
cost of painting 1 wall of a room = 
Cost of painting 3 walls of a room = 6.05 * 3= $18.15

<u><em>8/20</em></u>
Step-by-step explanation
<em>boys left handed=3
</em>
<em>boys right handed=9
</em>
<em>girls left handed=2
</em>
<em>girls right handed=6
</em>
<em>what is the probability that a student chosen from random is a girl? give answer as a fraction please and include step by step process</em>
<em>girls left handed: 2</em>
girls right handed: 6
6+2=8
total all students 20
<em>8/20</em>
