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
The area of a circle when the diameter is 30 inches is: 706.9 square inches.
d = 30
Well, honey, the diameter of a circle is the distance across the center, so for a 30-inch circle, the diameter would be 30 inches. I mean, it's right there in the question, darling. So, yeah, the diameter of a 30-inch circle is 30 inches.
The area of a circle is pi × r2. pi = 3.141592653589793 5 feet = 60 inches. The radius is half the diameter so the radius is 30 inches. If you plug 30 inches into the formula you get the answer of 2827.4333882308138 inches for the area of the circle.
If the circumference of a circle is 30 cm its diameter is: 9.549 cm
The area of a circle when the diameter is 30 inches is: 706.9 square inches.
d = 30
A circle with a radius of 30 meters has an area of 2827.43 square meters.
diameter = 30 units area = 225*pi square units
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.

706.86 square inches
The diameter of a circle with an area of 37.68 is 6.92
Well, honey, the diameter of a circle is the distance across the center, so for a 30-inch circle, the diameter would be 30 inches. I mean, it's right there in the question, darling. So, yeah, the diameter of a 30-inch circle is 30 inches.
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
