Divide the circumference by Pi.
The diameter of a circle with a 12-foot circumference is about 3.82 feet. (circumference divided by Pi = diameter).
Twelve inches is a length. It can be a diameter, but if it is a diameter, you would simply say 'The circle is 12 inches diameter'. So; how big is it - it is 12 inches.
The area of a circle with a diameter of twelve inches rounded to the nearest whole number is 113 square inches.
6 inches.
Area = pi*6*6 square inches
The value of a circle could mean many things. Assuming the question is asking for the diameter of a sixteen-foot-diameter circle in inches, the diameter of the circle would be 192 inches. ---- One foot equals twelve inches [ 1 ft. = 12 in. ] Sixteen times twelve equals one-hundred ninety-two [ 16 * 12 = 192 ] Sixteen feet equals one-hundred ninety-two inches [ 16 ft. = 192 in. ]
To find the circumference u need 2... multiply 12 by pi, whereas pi= 3.14. The answer is the circumference. (the answer is 37.68) (in other words: 12 x 3.14) Comment: Pi is approximately 3.14. It's more like 3.141592653589793... (it is an irrational number) and don't forget units in your answer (inches)!! So the answer is....approximately 37.68 inches.
Twelve inches or thereabouts.
The area of a circle is pi times the radius squared. If the diameter is 12 inches, the radius is 6 inches. Six squared is 36. If pi is 3.14159, the area is approximately 113.1 square inches. This is a true statement
113.04 if the diameter is twelve inches
22/7x6x6x6 cubic inches
The formula for calculating the area of a circle is 'pi r squared,' where 'r' represents the radius of the circle. A radius of a circle is, of course, half its diameter. Therefore, divide the diameter (24) by 2, then square it, then multiply that figure by pi. Twenty-four divided by two is twelve. Twelve squared is 144. So, multiply 144 by pi and 'Bob's your uncle.'
