Area = (pi) (radius)2 = 225 pi = 706.858 square centimeters (rounded)
Because the circle is measured in square units.
pi times radius squared: a=pi x r2
Area of a circle = pi*r2 Area = pi(12 in)2 ( 144 * pi ) = 452 in2 =======

Assuming that cirlce = circle and raduis = radius, the answer is 452 sq metres.
Area = (pi) (radius)2 = 225 pi = 706.858 square centimeters (rounded)
Because the circle is measured in square units.
pi times radius squared: a=pi x r2
Area of a circle = pi*r2 Area = pi(12 in)2 ( 144 * pi ) = 452 in2 =======
The radius is the distance from the centre point to the edge.
In which computer language?
The line from the center of the circle to the oustide of the circle.
To determine the area, you need to know the shape you are referring to. For example, if you have a square with each side measuring 30 meters, the area would be 30m × 30m = 900 square meters. If it's a circle with a radius of 30 meters, the area would be calculated using the formula A = πr², resulting in approximately 2,827 square meters. Please specify the shape for a more accurate answer.
You half the diameter, so the radius is basically 30m
