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.
To convert linear feet to square feet, you need to know the width of the area. If the width is, for example, 2 feet, then 6 linear feet would be 12 square feet (6 linear feet multiplied by 2 feet).
The abbreviation is ft. Abbreviation for Lineal Feet: Lft
A 15 by 16 foot rug would have perimeter of (15+15+16+16) = 62 feet. To convert to linear feet, you would double the perimeter (that is, consider both sides of the rug) so a 15 by 16 foot rug is equivalent to 124 linear feet.
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 !
Lanier made a foot pedal for PCs. They made several models. They no longer seem to make these products, or at least their web site doesn't mention them. I can't find any reference to their size.
