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 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.'

Divide the circumference by Pi.

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. ]

Use the formula A=pi x r2. Divide the diameter by 2 then that gives the radius. Substitute the value for radius in the formula. Then that's the answer. (Use 3.14 for pi)
