Q8. Predict the output of following code:

 

num = 20.5

z = 3

result = 2 + z * z ** 3 + num // z

print (result)

 

(a) Firstly, determine the answer without running the code and write.

(b) Now type the above code in script mode and test-run the program. Write below the result given by Python.

 

Answer =

 

(i)

It is based on your thinking that how you execute the above program in your mind. So do you self.

 

(ii)

Output:-

 

89.0

Q9. Write a program to read a floating point number n. Print n, n², n³, n⁴ and n⁵.

 

Answer =

 

num = float (input ("Enter the number :- "))

print ("Answer is :- ", num, ', ', num **2, ', ', num ** 3, ', ', num ** 4, ' &', num ** 5)

 

 

 

 

 

 

Q10. Write a program that calculates the volume and surface area of a sphere. The program must first ask the user to key in a radius value, r, before it performs the calculations. The program should display the result of the calculations. Save the program as "sphere.py".

 

Use the following formulae:

 

Surface area, S = 4 π r²

Volume, V = 4 / 3(π r³)

π = 3.142

 

Answer =

 

First make a module name with "sphere.py". Then write the program.

 

r = float (input ("Enter the Radius of sphere :- "))

print ("Surface Area :- ", 4 * 3.142 * r ** 2)

print ("Volume :- ", 4 / 3 * (3.142 * r ** 3))

Q4. Write a short program that asks for your height in centimeters and then converts your height to feet and inches. (1 foot -12 inches, 1 inch = 2.54 cm)

 

Answer =

 

height = float (input ("Enter the Height in cm :- "))

print ("Height in Feet :- ", (height / 2.54) / 12 )

print ("Height in inches :- ", height / 2.54)

 

 

 

 

 

Q5. Write a program to find the area of a triangle using formula 1 / 2 * base * height.

 

Answer =

 

height = float (input ("Enter the Height :- "))

base = float (input ("Enter the Base :- "))

print ("Area of triangle :- ", 1 / 2 * height * base)

 

 

 

 

 

 

 

Q6. Write a program to read two numbers and print their quotient and remainder.

 

Answer =

 

num1 = int (input ("Enter the first number :- "))

num2 = int (input ("Enter the second number :- "))

print ("Quotient :- ", num1 // num2 )

print ("Remainder :- ", num1 % num2)

 

 

 

 

 

 

 

Q7. Write a program to compute simple interest and compound interest.

 

Answer =

 

 

p = int(input("Enter principal amount = "))

r = int(input("Enter the rate = "))

t = int(input("Enter time  = "))

si = (p * r * t ) / 100

com = p * ( (1 + (r / 100 ))** t ) - p

print("Simple interest = ",si)

print("Compund interest = ",com)
