Diameter = 30cm so radius = 15 cm.
Then Area = pi*r2 = 706.9 cm2
A diameter of 30 units means that the distance across a circle, passing through its center, measures 30 units. This measurement represents the longest straight line that can be drawn within the circle. For example, if the diameter is in inches, the circle would be 30 inches wide. The radius, which is half the diameter, would be 15 units.
A circle with a radius of 30 meters has an area of 2827.43 square meters.
The area of the circle: pi*15*15 = 225*pi square measurements
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 area of a circle when the diameter is 30 inches is: 706.9 square inches.

Area = 706.5 Area of a circle = pi x r2 Diameter = 30, then radius = 15 pi x r2 3.14 x 152 3.14 x 225 = 706.5
diameter = 30 units area = 225*pi square units

If you are asking about a circle with a circumference of 30" than it would be 9.5".I you mean a radius of 30" than it would be 60".If you mean an area of 30" than it would be 19".
The circumference of a circle 30 inches in diameter is 30*pi inches
