oe’s Pizza Palace needs a program to calculate the number of slices a pizza of any size can be divided into. The program should
perform the following steps: Ask the user for the diameter of the pizza in inches. Calculate the number of slices that may be taken from a pizza of that size. Display a message telling the number of slices. To calculate the number of slices that may be taken from the pizza, you must know the following facts: Each slice should have an area of 14.125 square inches.To calculate the number of slices, simply divide the area of the pizza by 14.125.The area of the pizza is calculated with this formula: Area = "pi r squared" where pi is approximately 3.14159 and r is the radius (half the the diameter). To calculate the number of slices that may be taken from the pizza, you must know the following facts: Each slice should have an area of 14.125 square inches. To calculate the number of slices, simply divide the area of the pizza by 14.125. The area of the pizza is calculated with this formula: Area = "pi r squared" where pi is approximately 3.14159 and r is the radius (half the the diameter).
1 answer:
Answer:
# the user is prompted to enter diameter in inch
diameter = int(input("Enter the diameter of the pizza you want (in inch): "))
# the value of PI is saved as a constant
PI = 3.14159
# the area of the pizza is calculated using pi r squared
# the value of r is diameter divide by 2
area = PI * ((diameter / 2) ** 2)
# the value of area is displayed
print(area)
# the number of slice is calculated as area divide by 14.125
# integer division is use to get number of slice
number_of_slice = area // 14.125
# the number of slice is displayed to the user
print("Your number of pizza slice is: ", number_of_slice)

Step-by-step explanation:
1) Write an equation in point slope form to model the table.
The standard form of point slope form is:
Finding Slope m:
Slope can be find using:
where
Putting values:
So, slope is -55/4 and considering x₁= -2 y₁=20
Putting values in point-slope form:
So, Equation in Point Slope form is
2) Write a linear equation for the line having Slope = -1/2 and point (3,5)
We will use Point Slope form:
Putting values:
So, linear equation of line with slope of -1/2 and point (3,5) is
3)
a) identify the slope and point
The standard form of point slope form is:
So, Slope = -1/2 and point is (4,3)
b) Convert to slope intercept form
The slope-intercept form is:
Solving:
So, Slope intercept form is
c) Convert to standard form:
Standard form is : ax+by=c
Solving:
can be written as
So, Standard form is:
d) Find the intercepts
y-y_{1} = m(x-x_{1})
- For x-intercept set y=0
can be written as
x-intercept is (14,0)
- For y-intercept set x=0
y-intercept is (0,7)
So, x-intercept is (14,0) and y-intercept is (0,7)
