Feet, singular foot, is a unit of measurement, equal to 0.3048 meters. "Feet in a circle" may mean that the circlés radius, its diameter, or its circumference has a certain number of feet.
There are two ways to answer your question. If you mean the circle is 16 feet wide (diameter), then the square footage is 201.06 square feet. However, if you mean the circle is 16 feet around (circumference), the square footage will be 20.372 square feet.
There is no such thing as a "square circle". If you mean "8 square feet", that is already the area.
2.52 feet if you mean a 5 foot area 1.59 feet if you mean a 5 foot circumference
Circle with a line through it is square yards, a square with a line through it is square feet
If you mean how many feet AROUND the circle, that is the circumference. Multiply the diameter (3 feet) by pi- 3.14. About 9.42 feet
If you mean as in the area of a circle that has a circumference of 518.519 feet Then its radius is about 82.5 feet The area of the circle: pi*82.5^2 = 21,382 square feet rounded
Your questions is not solvable the way you wrote it. If you mean, "What is the radius of a circle with a diameter or 6 feet?" , then the answer is 3 feet. Reason is because the radius of a circle is half of its diameter.
Taking the width to mean the diameter, the answer is 69/2 = 34.5 feet
If you mean a circle, use the formula for the area of a circle: A = pi x r2.
Are you referring to the circle's diameter or its cicumference? If you mean diameter then the radius is 50/2 = 25 feet If you mean circumference then the radius is 50/(2*pi) = 7.957747155 or about 8 feet
Circle with a radius of 8 feet equals a circle with a diameter of 16 feet.
A circle with a radius of 14 feet has an area of 615.75 square feet.
