Question

Write a shell program to find the area and circumference of a circle

Answer 1

Answer:A circle is one of the simple shapes of Euclidean geometry. It is the locus of all points in a plane at a constant distance, called the radius, from a fixed point, called the center. Through any three points not on the same line, there passes one and only one circle.

A diameter is a chord passing through the center. The length of a diameter is twice the radius. A diameter is the largest chord in a circle.

Circles are simple closed curves which divide the plane into an interior and an exterior. The circumference of a circle is the perimeter of the circle, and the interior of the circle is called a disk.

Step-by-step explanation:

Answer 2

area of a circle= πr^2
perimeter or cicumference of circle= 2πr
