One application of volume is determining the density of an object. Assume the object is made of a pure element (eg: gold). If we know the volume (v) of the object, and we know the mass (m), then we can use the formula D = m/v to figure out the density D. Knowing the volume is also handy to determine if the object can fit into a larger space or not. Another application is figuring out how much water is needed to fill up the inner space of the 3D solid (assuming it's hollow on the inside).
The surface area is handy to figure out how much material is needed to cover the outer surface. This material can be paint, paper, metal sheets, or whatever you can think of really. A good example is wrapping a present and the assumption is that there is no overlap.
Answer:
y=5
Step-by-step explanation:
the line going up and down is the y and the line going left to right is the x so u would go up to until u find the number that fits and it would be y=5

Answer:
The answer to your question is letter A
Step-by-step explanation:
Data
x² - 6x + y² - 6y = -9
Process
1.- Find the center
x² - 6x + ( )² + y² - 6y + ( )² = -9
x² - 6x + (3)² + y² - 6y + (3)² = -9 + 9 + 9
(x - 3)² + (y - 3)² = 9
Center = (3, 3)
radius = 3
See the graph below
2.- From the previous information and the graph, we conclude that the equation intercepts the y-axis in (0,3)
