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: Information security
Explanation:
The information security is one of the system that keeps the data confidential, assure the integrity and also availability of the information or data.
This system is basically refers as the CIA triad in the information security system and the data risk management.
The main aim of the information security is that keeps the data protected from the unauthorized accessing and also controlling the access in the system.
Therefore, Information security is the correct answer.
Answer:lol :)

Answer: B) The volume of the radio and D) the outdoor temperature.
Explanation:
The analog signal is the signal that continuously varying with the time and it continuous analog signal. Analog signal is basically used to carry information or data from one device to another device.
The volume of the radio is the example of the analog signal as it carry voice from one place to another. The analog signal is the type of signal that use to measure the particular change in the physical phenomena like pressure, sound and temperature in the environment. So, outdoor temperature is also the example of analog signal.
And the other options (A) and (C) are incorrect because it is represent any physical change in the environment.
Answer:
The correct option for accessing the value in sarray[3] is : d) *(sptr+3)
Explanation:
a) *sptr[*3] is wrong option because its syntax is not right it will give errors.
b) *sptr+3 is also wrong option because it will add 3 to the value of sarray[0].
c) sptr+3 is wrong option because it will only access the address of sarray[3] not the value it contains.
d) *(sptr +3) is correct syntax for accessing value in sarray[3] by using pointer
