A net is just a 3D shape made into a 2D shape. So when you have a net, it is easier to make sure you count up all the sides without missing one or counting one twice.
To solve the problem, we need to get the formula for area of a circle - Area = pi * r^2; r= radius = 3.14 * (13cm)^2 = 3.14 * 169cm^2 or 3.14 * 13^2cm^2 = 530.66cm^2 Therefore, the area of the circular plate is 530.66cm^2
