Answer:
$18.84
Step-by-step explanation:
The area of a cone is (1/3)pi*r^2*h
With all variables plugged in we get an area of (1/3)*3.14*(1^2)*9, or 9.42 cubic inches. With a value of 2$/in^3, we get 2*9.42, or 18.84.
Therefore, the value of the container is $18.84.
The first one is B and the second is D
answer: x = 1/2
<u>explanation</u>
subtract 3x from both sides
4x+8=10
subtract 8 from both sides
4x=2
divide both sides by 4
x=2/4
simplify
x=1/2 OR x=.5
hope i helped!
Just multiply by 8 each time hope this helps :)))
