Question

write a program to gind the area of circle where r is radius.A=pi*r*r; where pi=3.14​

Answer 1

Explanation:

ANSWER:-

# Program to find the area of circle

r = int(input("Enter Radius"))

a = 3.14 * r

print(a)

• Above coding will give us the required output.
• Here, int is used to depict integer value.
• a is the area, as we know area of circle $\pi$ r².
• r here is the RADIUS of the circle.
• # is used to show the comment on what the project is based on.
• The above coding is a Python coding.
• Print còde is used to give the output.
• We also use if-else format with elif.
• Also, we can have it in Visual Basic as:-

Private sub ----

Dim r,a as integer.

r = Val(Textbox1 . text)

a = Val(Textbox2 . text)

a = 3.14 * r * r

Msgbox(The & answer & is & "a")

End Class

Answer 2

Answer:

#Program for finding area of circle

r = int(input("Enter Radius"))

a = 3.14 * r

Know More:-

• R is the Radius
• A is the area
• π = 3.14
• The formula is πr²
• Print códe is used to take output
• Type :- Python
