Question

Algorithm and flowchart to find area and perimeter of circle

Answer 1

Explanation:

It is usually called the circumference of a circle, not a perimeter.

For a circle with radius r, the formula for the circumference C is

C=2πrC=2πr.

If you are given the diameter d, the formula is C=πdC=πd.

This is not a true algorithm (like a recipe). It is an easily usable formula. The calculation of a circumference doesn't require an algorithm.

Recall that 2r=d2r=d.
