Question

algorithm and flowchart to calculate the area and perimeter of the diamond

Answer 1

Explanation:

You should be able to write down the algorithm from this (copy the contents of the shapes from top → bottom to an ordered list).

To apply it to the case where the diameter d = 9, make that substitution (r = d/2 = 9/2 = 4.5) in steps that follow “Read radius, r”.

Hope this helps and does not mislead or confuse you.
