9pi
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 equation is: (x+3)^2 +(y+5)^2 = 16
The line from the center of the circle to the oustide of the circle.
pi times radius or diameter equals are of a cirlce
A circle with a radius of 5 units has an area of 78.54 square units.
