Answer:
The code to calculate the area of a circle is:
from math import pi
def circleArea(radius):
if radius > 0:
return pi * (radius ** 2)
else:
return None
if __name__ == '__main__':
radius = 5
print("Radius: {} Area: {}".format(radius,circleArea(radius)))
Explanation:
A detailed explanation of each line of code is given below.
#Define the number pi used to calculate the area
from math import pi
#We define a function that calculates the area of a circle
def circleArea(radius):
#Check if the radius is valid ( radius > 0) since there aren´t negative radius
if radius > 0:
#Compute the area formula for a circle 
return pi * (radius ** 2)
else:
#Return None if the radius is invalid
return None
#Run the function we´ve defined
if __name__ == '__main__':
#Define a radius
radius = 5
#Call the function and parse the radius through it, then print the result
print("Radius: {} Area: {}".format(radius,circleArea(radius)))
Answer:
#include <iostream>
using namespace std;
int main()
{
float radius = 5.4;
float circumference = 2 * 3.14 * radius;
float area = 3.14 * radius * radius;
cout<<"the circumference of the circle is "<<circumference<<endl;
cout<<"the area of the circle is "<<area<<endl;
return 0;
}
Explanation:
Include the library iostream for using the input/output instructions.
create the main function and define the variable with value. Then,
use the formula to calculate the circumference and are of circle.
here, choose 
after that, display the result.
Note: All variable define in float type.
Answer:
local scope which is the entire body of the function/method that it is being used in
Explanation:
The variable numC has a local scope which is the entire body of the function/method that it is being used in, which in this scenario is the passwordMaker method. This is because the variable numC is being used as a parameter variable for that method, meaning that a piece of information is being inputted by when the method is called and saved as the variable numC which is then used by the lines of code inside the method, but cannot be accessed from outside the method thus.
<u>Sustaining</u> technologies are technologies that enable the incremental improvement of products and services.
Sustaining technology refers to the constant improvement of industrial activities which includes cost efficiency, product quality, and time.
Sustaining technology differs from disruptive technology in that disruptive technology identifies new opportunities and creates new products and services that the customers don't know about while sustaining technology enables the companies to compete with other associations by improving the products and services that the consumers already know about.
Sustaining technology works by identifying the needs and demands of the consumers and customers and can sometimes be a slow method.
Sustaining technologies enable companies to maintain their existing customer base and at the same time improve their existing products.
