The formula for the area of a circle is pi * radius squared. The circumference of a circle's formula is pi * diameter. NOTE: pi equals approx. 3.14
Divide the circumference by (2 x pi) to get the radius. Then use the formula for the area of the circle.
It isn't. That is the formula for the AREA of a circle!
Area = pi*62 Circumference = pi*12 or 2*pi*6
The answer depends on the formula for what: the radius, circumference, length of an arc, area, area of sector, area of segment: each one has a different formula.
