A= Pi r ^2 ; diameter = 2*r A= 3.14 * (1/2*18)^2 A= 3.14 * 9^2 A= 3.14 * 81 A= 254.34 in^2
The distance around a circle is called the circumference. The formula for the circumference of a circle is C = πd, where C is the circumference, d is the diameter, and π is approximately 3.14159.
For a circle with a diameter of 18 inches, the circumference would be C = π(18) = 56.5487 inches.
You mean the circumference C. C = pi times d C = 56.549 inches.
Your question doesn't make sense. The area of a circle is Pi (approximately 3.14) times the RADIUS squared. An example would be a circle with a diameter of 6 inches and thus the circle would have a radius of 3 inches. Three squared (3 times 3) is 9, and 9 times Pi is approximately 28.3 square inches.
There are 19.4167 feet in 233 inches. To convert inches to feet, you divide the number of inches by 12 (since there are 12 inches in a foot).
The standard size of a study table is typically around 48-60 inches in width, 24-30 inches in depth, and 30 inches in height. This allows for enough space for a comfortable study environment with ample room for a computer, books, and other study materials.
7 feet = 84 inches There are 12 inches in one foot, therefore 7 feet in inches is 7 x 12 = 84 inches
1 foot is 12 inches, so 3 feet would be 36 inches
Well now, that depends. What do you mean when you say "a 44 inch circle" ? -- If "44 inches" is the distance across the fattest part of the circle, then its diameter is 44 inches. -- If "44 inches" is the distance from the center of the circle out to the edge, then the diameter is 88 inches. -- If "44 inches" is the distance all the way around the circle, then the diameter is 44/pi = 14 inches (rounded)
The diameter will be 12.41408556 inches
I'm not completely sure what a "2.5 inch circle" is. Is that the distance all the way across the circle (diameter), or is it the distance from the center of the circle to its curve (radius) ? If diameter = 2.5 inches, then area = 4.909 square inches If radius = 2.5 inches, then area = 19.635 square inches
In order to fully understand what the radius of a given circle is, you must know the diameter. The diameter is the distance across the circle through the center. The radius of a circle is half the diameter. For example, if the diameter of a circle is 8 inches, then the radius would be 4 inches.
36 inches. The radius is the distance from the centre to the outside or circumference and trhe diameter is the distance across passing through the centre. Therfore the diameter is twice the distance of the radius.

If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x pi = circumference).
circumference = 17pi inches
The circumference of a circle with a diameter of 3 inches is 9.425 inches.
The circumference of a circle when the diameter is 17 inches is: 53 inches.
If the circumference of a circle is 62.8 inches the diameter is: 20 inches.
The circumference of a circle that has a diameter of 35 inches is 109.96 inches.
