Knowing that the area of a circle is its radius squared times Pi, the area of a 10 ft radius circle is 100*Pi square ft, or about 314 square feet.
a square foot is simply a square that is 1 foot by 1 foot if the area you need to measure is 3 feet by 6 feet you have 18 square feet (3 x 6 = 18) if the area is 10 feet by 10 feet you have 100 square feet (10 x 10 = 100) hope this helps!
To find the area of a circle, you use the formula A = πr^2, where r is the radius of the circle. Since the diameter is 10 feet, the radius would be half of that, which is 5 feet. Plugging this into the formula, we get A = π(5)^2 = 25π square feet. This is approximately 78.54 square feet.
There are 0.596877868 acres in 26,000 square feet. 26,000 square feet x 2.29568411 x 10-5 acres/1 square foot = 0.596877868 acres 1 square foot = 2.29568411 × 10-5 acres
A 40-foot by 10-foot yard contains 400 square feet.
