Answer:Just solve it. This is Algebra. Not that hard. Use Substation Method
Step-by-step explanation:
To start, I had similar questions and I know that it takes 3 cones to fill a cylinder.
And as for the volumes:
V of a cylinder= V=π r<span>2 h (pi x radius squared x height)
Volume of a cone= V=</span><span>π r2 h/3 (pi x radius squared x height divided by 3)</span>

Answer: Point D</h3>
See the diagram below. I drew a line through the left corner points of the red and blue quadrilaterals. This line goes through the point D. You could pick on the right corners of the original quadrilaterals and that line will also pass through point D.
Answer:
r = 
Step-by-step explanation:
In order to make 'q' the independent variable in the equation, you need to solve for 'r'. The dependent variable would be 'r' because it depends on the value of 'q' to be solved. We can solve for 'r' by using inverse operations and completing the same operation on both sides of the equation. Starting with the initial equation and solving for 'r':
-7q + 12r = 3q -4
Add '7q' to both sides: -7q + 7q + 12r = 3q - 4 + 7q or 12r = 10q - 4
Divide all terms by 12: 12r/12 = 10q/12 - 4/12
Simplify: r = 
You must be Divide with fractions.
7/8/1/2 then flip with 1/2 to 2/1 and multiply.
And the answer is 1 and 3/4
