Area of a circle = pi*radius squared
Not that 30 inches = 2.5 feet
If 6 feet 6 inches is its diameter then its radius is 3 feet 3 inches
It is 16 feet across a circle.
One acre is 4,840 square yards or 43,560 square feet, and so a square piece of land measuring 208.71032 feet on all four sides is approximately an acre. The number of sets of dimensions that will equal an acre is infinite. For instance, a piece of land 10 feet wide and 4,356 feet long is exactly one acre because 10 x 4,356 = 43,560. Moreover, a piece of land 30 feet wide and 1,452 feet long is an acre because the two dimensions equal 43,560 square feet when multiplied.Even circles can be acres! In fact, a circle having a diameter of 235.564 feet is approximately an acre because the formula for determining the area of circles proves that such a circle is almost equal to 43,560 square feet.
432 square feet. Just multiply length by width - the answer is the square footage.
Well, honey, 2000 cubits by measure is equal to about 3000 feet. Cubits may sound fancy, but when it comes to good ol' feet, they're about 1.5 times longer. So, put on your walking shoes and start counting those feet!
A circle with a radius of 14 feet has an area of 615.75 square feet.

The area of a circle with a radius of 4 feet is: 50.27 square feet.
divide the square feet by pi that gives you the radius squared find the square root and get the radius
