1 acre = 43,560 square feet
10 acres = 435,600 square feet
Area of a circle = pi R2
435,600 = pi R2
R = sqrt(435,600 / pi) = 372.365 feet (rounded)
The formula for the area (A) of a circle is A = πr2. If the area is 100π then 100π = πr2 : 100 = r2 : r = √100 = 10. The radius is of length 10 units.
Area of a circle = pi*radius2 Area = 314.159 square feet to 3 decimal places.
Area = pi R2 = 100 pi = 314.16 square feet (rounded)
Well a circle has 360 degrees so a sector of 90 degrees has an area equal to 90/360 (or 1/4) of a circle with the equivalent radius. The area of a circle is defined as PI*Radius^2 so the area of a 90 degree sector will be 1/4*PI*Radius^2. The area will be 1/4*3.14*10^2 or 78.5 in^2.
15.707963267948965 square inches. I think.* * * * *That is a very accurate but very wrong answer.The correct answer is 314.159 sq inches (to 3 dp).******Yes, the correct answer is 314.159. Here's why:The area of a circle can be found by multiplying pi (3.14159...) by the square of the radius. (The radius of a circle is 1/2 the diameter)This 20" circle has a radius of 10", so its area is 3.14*10"*10"=314.159
Approximately 0.065 (0.0649088843) acres.
A circle with a radius of 10 feet has an area of 314.16 square feet.
A circle with a radius of 10 metres has an area of 314.16 square metres.
The radius is 3.162
If that's the area of a circle then its radius is about 10 cm
Area is 314.2 units2
Area of any circle = pi*radius squared
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.
Radius 10, area = 100 pi; radius 9, area = 81 pi
A circle with a radius of 10 meters has an area of 314 square meters.
A circle with a radius of 10 meters has an area of 314 square meters.
