Finding a circle's area is a helpful tool for measuring the space within the circumference of a circle. Let's break down the equation and define the variables. The area of a circle is represented asA. On the other side of the equation we haveπ(Pi) multiplied byr2(radius) squared. ...
Diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circumference of a circle. Learn how to find the diameter of a circle using radius, circumference, and area.
Radius of a circle is the distance between center of circle and the point on circle. Radius is half of diameter, the longest chord of circle. Circumference is the distance around the circle. Radius formula and equation at BYJU’S.
