Answer:
The surface area of the ball is of 29 square inches.
The volume of the ball is of 15 cubic inches.
Step-by-step explanation:
The ball has an spherical format:
Circumference of a sphere:
The circumference of a sphere is 6.2832 times the radius.
Surface area
In which r is the radius.
Volume:
The circumference of the ball is 9.4 inches.
So the radius is:
Surface area
Rounding to the nearest unit, the surface area of the ball is of 29 square inches.
Volume:
Rounding to the nearest unit, the volume of the ball is of 15 cubic inches.
Since you have not included the plot, I'll just tell you how to find the function of the graph that you are looking for.
Function of the straight line has the general formula: y = mx + c
where:
m is the slope of the line and c is the y-intercept
So first we will need to find the slope (m):
Taking two points from the graph (x1,y1) and (x2,y2), the slope can be calculated as follows:
m = (y2-y2) / (x2-x2)
Then, we will need to find the y intercept.
we have the equation y = mx + c and we have m calculated
Take any point that belongs to the line and substitute with the values of x,y and m and then calculate c.
Now you have both m and c calculated, just substitute with the values in the formula.
The first answer is true and the second answer is true as for how this actually is just plug in the numbers
x=4, y=3
2(4)=8 8+3=11
4-1=3
The answer should be gallons per minute
