The area of a circle is

pie(22/7) or (3.14) times R2

R = the radius of the circle (1/2 of the diameter)

What is the formula for finding the surface area of the circle?

A circle doesn't have a surface area because it is a 2D object. The area of a circle is = pi r2. if you mean the surface area of a sphere it is = 4 pi r2


What is the formula for surface area if the only measurement you have is the perimeter?

There can be no such formula in general. A formula will exist if the area is a regular polygon (or a circle).


What does surface area formula look like?

That depends what kind of figure you are talking about. The formula for the area of a circle is quite different from the area of a rectangle, for example.That depends what kind of figure you are talking about.

How do you find the surface area of a circleo o-xddddddd-o o-xddddddddddd?

The surface area of a circle can be found using the formula A = πr^2, where A is the area and r is the radius of the circle. Simply square the radius and multiply it by π to calculate the surface area.


What is the formula for finding the surface area using 3.14?

Assuming that 3.14 is pi, then most likely you're looking for the surface area of a circle, which is pi x r2.
