Given:
The figures cylinder, cube, cone, and pyramid.
To find:
The formula of volume for the given figures.
Solution:
Volume of a cylinder is:

Where r is the radius and h is the height.
Volume of a cube is:

Where a is side length of cube.
It is also written as:

Where l is length, w is width, h is height and
.
Volume of a cone is:

Where r is the radius and h is the height.
Volume of a pyramid is:

Where B is the base area and h is the height.
Therefore the table of formulae is shown below:

Answer:
(4,2)
Step-by-step explanation:
To find the solution, we can simply find the intersection. That is (4,2)
Multiple (5x+y= 28) by 6 giving you 30x +6y =168 and then you would add the two equations together, giving you 38x = 152, divide both sides by 38, giving you 4. after this, you would sub x=4 into one of the equations (i’m using the 5x+ y =28) which would give me 20 + y = 28, subtract 20 by both sides, giving you y= 8. so your answer is (4,8)
