Question

over the 2nd line what should come any idea pls tell. This is abt python i hope u will help in this at least

Answer 1

Given co‎‎de:

r = float(input("2")

print = "(a = math pi")

print("Area = ", 12.56)

p = 2*3.14*12.56

print("Perimeter = ", )

Corrected c‎ode:

import math

r = float(input("Enter the radius: "))

a = r*‎*2*math.pi

print("Area = ", a)

p = 2*math.pi*r

print("Perimeter = ", p)

Before directly calling a function, you need to ensure that it is first imported. We import the Math module by simply typing $\tt import\ math$. There are various other modules as well, another common one being $\tt statistics$, that is widely used for statistics purposes.

Squaring/exponentiation in python can be represented using double asterisks.

Also, the reason there was a syntax error in your co‎de is that the string quoting and bracketing weren't correctly typed. There was an unmatched closing bracket after the closing quote. Unmatched quotes/brackets can lead to errors.

Answer 2

Your Approach:-

1. r = float(input("2")
2. print = "(a = math pi")
3. print("Area = ", 12.56)
4. p = 2*3.14*12.56*
5. print("Perimeter = ", )

After correction:-

1. import math
2. r = float(input("Enter the radius: "))
3. print("Area = ", ((r* *2)*(math.pi)))
4. p = 2*math.pi*r
5. print("Perimeter = ", p)

What was the error in your approach?

• Did not import math package
• Line 1: Although no mistake but I assume you were trying to take input there..well you can use this...

r=2

• Line 2: Wrong syntax of printing and you cannot store value of math.pi in 'a' in double quotes, of course while printing too you cannot
• Line 3: how can you assume area to be 12.56 also, variable new cannot start with numbers
• If you assume radius is 12.56, you can directly do this...

r=12.56 instead of accepting Input.

• Line 4: It's better to use math.pi than writing 3.14
• Line 5: Oof! again wrong syntax... remove last *
• print("Perimeter=",p)
