Transcribed Image Text:Display the current day using a suitable function for UAE's timezone.
Create a function "area_sphere " that receives the radius of the sphere and calculates and returns the area of the sphere.
If the radius is less than 0, the function should return the value "Invalid Radius". The formula for calculating the area of the sphere is :
A = 4.ar
Where r is the radius of the sphere and A is the area of the sphere.
Define your own constant for the constant pie.
Initiate the variable r with some value and then display the radius and the area of the sphere using this function "area_sphere".
Sample Outputs for radius 2
Sample Output for radius -2:
Current Date :12/Apr/2021
Radius of Sphere: 2
Area of Sphere:50.24
Current Date :12/Apr/2021
Radius of Sphere: -2
Area of Sphere:Invalid Radius.
