Write a pyhton program to calculate area of a circle?
marta [7]

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 \pi * radius^{2}

   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)))

Write a recursive function to compute sum of first N integers starting with 1.
Citrus2011 [14]

Answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

// recursive function to find sum from 1 to n

int recur_Sum(int n)

{ // base condition

if (n <= 1)

 return n;

// recursive call

return n + recur_Sum(n - 1);

}

// main function

int main()

{

   // variables

   int n;

   cout<<"Enter a number:";

   // read the number

   cin>>n;

   // print the sum

   cout<<"Sum of first "<<n<<" integer from 1 to "<<n<<" is:"<<recur_Sum(n);

return 0;

}

Explanation:

Read a number from user and assign it to variable "n".Call function recur_Sum() with parameter "n".This function will recursively call itself and find the Sum of first n numbers from 1 to n.Then function will return the sum.

Output:

Enter a number:10

Sum of first 10 integer from 1 to 10 is:55
