Answer:
you have to put the formula of perimeter
X=162, if you multiply 18*9 which is the way to get the answer you get 162
Answer:
x=2x-5
= -2x=2x-5-2x
= x-2x=-5
Step-by-step explanation:
Answer:
h=1ft
Step-by-step explanation:
The volume of a cone is:
v=πr^h/3
plug in the values (I am assuming not 1/18π but 1/18×π):
1/18π= π1/3^2h/3
Get rid of the radius:
1/3^2=1/9
Continue:
π/18= πh/3*1/9= πh/18
Remove the denominators:
π=πh
Divide both sides by π :
h=1
