Answer:
x...third number
4x...second number
x-9...first number
(x)+(4x)+(x-9)=141
x+4x+x-9=141
6x-9=141
Let's add 9 to both sides...
9+6x-9=141+9
6x=150
Let's divide both sides by 6...
(6x)/6=150/6
x=25
third number...25
second number...(4)(25)=100
first number...(25-9)=16
Let's check our work...
25+100+16=141
141=141

Step-by-step explanation:
384π cm³ ( first one in list )
Calculate the volume (V) of the cone using the formula
V = 
πr²h ( r is the radius and h the height )
here r = 12 and h = 8
V = × 12² × 8 = 384π cm³ ← exact value
