Question

She is not sure about the size though, and wants to be able to quickly experiment with the drawing by changing only one number - the radius of the bottom dot - and for the rest of the code to size and scale the drawing accordingly. How should she adjust lines 2 and 3 of her code to implement this change?

Answer 1

2 var middle = bottom / 2;

3 var top = middle / 2;

Step-by-step explanation:

To implement the following changes in the 2 and 3 lines, she firstly declares a variable then, she has to initialize or assign by performing the division method with the variable 'bottom' by 2.

After that in the next line, she declares a variable then initialize or assign by performing the division method with the variable 'bottom' by 2.

So, the following answer is correct according to the given scenario.
