You need to qualify the 30 inches. Is it the diameter or circumference of a circle?
Diameter = 30/pi inches
The area of a circle when the diameter is 30 inches is: 706.9 square 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 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".
1.27 inches To find diameter (width of a circle): C = 3.14159 (pi) * diameter 4 = 3.14159 * d d= 1.27 inches
The circumference of a circle 30 inches in diameter is 30*pi inches
The volume of a cylinder with a diameter of 30 inches and 36 inches long is 25,446.9 cubic inches.
Diameter = 30/pi inches
The area of a circle when the diameter is 30 inches is: 706.9 square inches.
Circumference = pi * diameter C = pi(3.14159 should do) * 30 inches = 94.2478 inches circumference
30 inches. The diameter is twice the length of the radius.

Diameter is the width of a circular or spherical figure or object. Something 180 inches in diameter is also 180 inches in width or thickness.
The radius of a circle is half of its diameter. Therefore, if the diameter of the circle is 60 inches, the radius would be half of 60, which is 30 inches. The formula to find the radius from the diameter is: radius = diameter / 2.
706.86 square inches
About 30 inches
