Formula for Area

Area is the amount of surface the circle covers. It is measured in squared units.

The formula for area is pr2(pi x r squared).


    the radius is 2m, what is the circumference?
    A=3.14 (2)2
    A=3.14 x 2 x 2
    A=6.28 x 2
    A=12.56 m2

   You always need to put the units you are working with.
    Explaining it like this will give an accurate answer.
