Java Script program to enter radius of a circle and find its diameter, circumference and area
In geometry, the area enclosed by a circle of radius r is πr2. Here the Greek letter π represents a constant, approximately equal to 3.14159, which is equal to the ratio of the circumference of any circle to its diameter.
The circumference of a circle is the linear distance around its edge.
<script>
let a,d;
r=parseInt(prompt("Enter Radius of a Circle"));
a=(3.14*r*r)
alert(a)
d=(2*r)
