Question

Write a PYTHON program that takes the radius of a sphere (a floating-point number) as input and then outputs the sphere’s surface area.

The Surface Area of a Sphere is

Surface Area = 4πr²

Surface Area = 4 * PI * radius * radius

Answer 1

"""Program for finding the surface area"""

from math import pi
r = float (input (" Enter the radius of sphere: "))

SA = 4 *pi *r * r
print(" Surface Area of Sphere = ", SA ," unit square ")





----------------------------------------------------------------------------------------------
 
"""Program for finding the surface area by declaring the value """

pi = 3.14

//radius of sphere

radius = 6.34

SA = 4 * pi * radius *radius 
print(" Surface Area of Sphere = ", SA ," unit square ")
