# Class 11 Computer science question for python with code solution

## 1. Write a Program to enter length and breadth and calculate area of rectangle

`width = input("Enter the width = ")length = input("Enter the length = ")area = float(width)*float(length)print("Area is = {0}".format(area))`

## 2. Write a Program to enter radius of circle and calculate area of circle

`import mathradius = input("Enter the Radius = ")area = float(radius)*float(radius)*math.piprint("Area is {0}".format(area))`

## 3. Write a program to enter Name, marks of 5 subject and calculate total & percentage of student

`name = input("Enter the Name of Student = ")english = input("Enter the Marks of English = ")hindi = input("Enter the Marks of Hindi = ")maths = input("Enter the Marks of Maths = ")science = input("Enter the Marks of Science = ")sst = input("Enter the Marks of SST = ")total = (float(english)+float(hindi)+float(maths)+float(science)+float(sst))/5print("Percentage for {} is {}".format(name, total))`

## 4. Write a program to enter radius and height of cylinder and calculate volume of cylinder.

`import mathradius = input("Enter the radius of cylinder = ")height = input("Enter the height of cylinder = ")volume = float(radius)*float(radius)*math.pi* float(height)print("Volume is {0}".format(volume))`
