14 The area of a circle is calculated using the formula ni x 12 where it is equal to 3.142 and r is the
radius.
A program is written to allow a user to enter the radius of a circle as a whole number between
1 and 30, then calculate and output the area of the circle.
01 radius = 0
02 area = 0.0
03 radius = input("Enter radius")
04 if radius <1 OR radius > 30 then
05 print("Sorry, that radius is invalid")
06 else
07 area = 3.142* (radius ^2)
08 print (area
