Question

Write the output of following
Cls
Let r=10
area=3.14*r*r
Print "the area of circle is"area
End

Answer 1

Cls is basically a command given to the system to clear the output screen.

As it is till now there is nothing is on output screen cls function will play no significant role.

Now r is assigned a value 10 already , so area will be calculated with the value of r =10 and finally print function will display the output as:

the area of circle is 314.
