If the radius is two. it won't be a unit circle, a unit circle is defined as a circle with radius one.

A unit circle is a circle with radius equal to one.

Pi is used in many different places.The most obvious one is to calculate several things related to circles and spheres: for example, calculate the circumference and the area of a circle if you know the radious, or calculate the surface area and the volume of a sphere if you know the radious.Pi is also used in certain situations where there is no connection to circles. For example, in certain integrals (to calculate the area under certain functions).Pi is used in many different places.The most obvious one is to calculate several things related to circles and spheres: for example, calculate the circumference and the area of a circle if you know the radious, or calculate the surface area and the volume of a sphere if you know the radious.Pi is also used in certain situations where there is no connection to circles.

Pi, by itself is not enough. You need the radius which is the length from the centre of the circle to its circumference (its boundary). If the radius is r, then the area is pi*r*r If, instead of the radius, you have a diameter - the length from one side to the other, through the centre - then radius = diameter/2. Once you have r you can calculate the area. If you have the circumference, then that is 2*pi*r and from that you can determine r and so calculate the area.

You can't. Area is a two-dimensional quantity, and you need two numbers to calculate it. The only figure whose area you can calculate when you have only one number is a circle.

The area of one unit is one unit2. one unit * one unit = one unit2

Radius, diameter, and area. They're all tied together, so if you know any one of them, you can calculate the other two.

Area of a circle = pi*radius2

Area of a circle = pi*radius2

In order to calculate the linear measurement of a circle, divide the circumference by pi to calculate the diameter of the circle. Then multiply the radius by 2 to find the diameter, and divide the radius by 0.5 to calculate the diameter.
