A circle with a radius of 30 meters has an area of 2827.43 square meters.
You can calculate the area of a circle with the formula: A = pi x radius2 If the 30 inches refers to the diameter, divide it by 2 to get the radius.
225pi sq m
The circumference of a circle 30 inches in diameter is 30*pi inches
Diameter = 30cm so radius = 15 cm. Then Area = pi*r2 = 706.9 cm2
