The area of a circle with radius r feet is pi*r*r square feet.
272 square feet. Multiply length by width - the result is the area in square feet.
0.40 r = sq ft
Area of circle = pi x r x r = 3.1415 x 10 x 10 = 314.15 square feet
Measure its radius in feet or derive it from the diameter or circumference. A circle with radius r feet has an area of pi*r^2 square feet.
A circle with a radius of 75 feet has an area of 17671.458676442588 square feet. You calculate this by using the area of a circle formula, which is A=pi*r^2.
assuming you used the formula pi*r^2 to find the area of the circle you already have the answer in square feet. Feet cannot be converted into square feet. feet measure distance which is one dimension while square feet measure area which is two dimensions, the two are not interchangable.
The area of a circle is calculate as:A = pi x r squared If the radius "r" is in feet, the area will be in square feet.
Diameter is 24 feet, Radius is 24/2 = 12 feet Area of circle = pi x r x r = 3.1415 x 12 x 12 = 3.1415 x 144 = 452.376 square feet
If it is a square or rectangle, you multiply the length (in feet) by the width (in feet). If it is a circle, the formula is A=pi x r^2.
Any area is measured in square units - square inches, square centimetres, square miles or whatever. If the shape is regular then there is a formula to help you do so. A circle has an area of pi*r*r where pi = 3.14159 and r is the radius of the circle. If r is expressed in feet then the area will be in square feet - even if the shape is not square.
