Area of a circle is Pi x r x r (Pi r squared.) 3.142 x 10 x 10 square feet = 314.2 square feet.
The circumference of a circle with a diameter of 2 feet is π * diameter = π * 2 = 6.28 feet. So, there are approximately 6.28 linear feet in a 2-foot diameter circle.
Area of a circle = pi R2 = 1 square foot R2 = 1/pi R = sqrt(1/pi) Circumference = 2 pi R = 2 pi sqrt(1/pi) = 2 sqrt(pi) = 3.5449 ft (rounded) = 3ft 6.54in Nice little problem !
If a circle circumference is 9.5 inches the diameter is 3.024 inches.
The formula for the circumference of a circle is C = 2πr, where r is the radius. Substituting 8.1 for the radius, we get C = 2 * π * 8.1 ≈ 50.92. Therefore, the circumference of the circle is approximately 50.92.
