Answer: 12 inches cubed
Step-by-step explanation:
volume=length x width x height
volume=1.5 in x 2 in x 4 in
volume=12 in^3
Answer:
Volume = 200.96 cubic feet
Step-by-step explanation:
Volume of a cone is given by the formula 
Where r is the radius and h is the height
Given r = 4 and height is 3 times that. So height is 4*3 = 12
Plugging these into the formula we get:
Volume of Cone = 
Thus, Volume = 200.96 cubic feet
Answer:
small number = -3
large number = 12
Step-by-step explanation:
Suppose two numbers are x and y
smaller number = x
larger number = y
Given that,
The difference of two numbers is 15
<h2>Equation 1</h2><h3>y - x = 15</h3>
Five times the smaller is the same as 9 less than twice the larger.
<h2>Equation 2</h2><h3>5x = 9 - 2y</h3>
Solve them
-x = 15 - y
x = y -15
put value of x in equation 2
5(y - 15) = 9 - 2y
-75 + 5y = 9 - 2y
-75 - 9 = -2y - 5y
-84 = -7y
y = 84/7
y = 12
x = 12 - 15
x = -3
