There are 12 cans of soup in a carton. Each can has a
1 answer:
Answer:
The required amount of paper is 2715.23 .
Step-by-step explanation:
The cans of soup has a shape of a cylinder, so that;
The surface area around a cylinder = 2rh
Where: r is the radius of the can, and h is its height.
From the given question, diameter = 8 cm, then;
radius =
=
r = 4 cm
Surface area around one of the cans = 2 x x 4 x 9
= 226.2857
Surface area around one of the cans = 226.28
So that, the total amount of paper required to make labels around each of the 12 cans can be determined by:
12 x 226.2857 = 2715.4284
The required amount of paper is 2715.23 .

Answer:
Option A is correct
The linear relationship displayed by the scatter plot is; y=x+10
Step-by-step explanation:
Scatter plot states that a set of points that represent data.
To determine the best equation for a set of points from the given figure.
In general, you can use these steps as follows:
- First sketch the line that appears to most closely follow the data.
and also try to have the same number of points above and below the line.
- You can choose two points on the line and estimate their coordinates.
- Then, find the equation of the line that passes through the two points
To find the equation of linear relationship that displayed by the scatter plot
Using Slope-intercept form:
For any two points and
the equation of line is given by:
where m is the slope and it is given by:
From the figure we choose two points on the line:
i.e, (9 , 19) and ( 15 , 25)
Calculate first slope m :
Now, using slope intercept form to find the equation of line;
or
y-19 = x -9
Add both sides 19 we get;
y -19 + 19 = x -9 + 19
Simplify:
y = x+10
Therefore, the function which best expresses the linear relationship displayed by the scatter plot is; y = x +10
