The area of a circle with a diameter of 13 centimeters is: 132.7 cm2
The area of a circle with a 13 ft diameter is: 132.7 square feet.
Well, area of a circle is (pi)r^2 and your diameter is 13, so your radius is 13/2 so your area would be (pi)(13/2)^2 or 132.7322896 =] -ray
The diameter of any circle is twice its radius. A circle with a radius of 13 inches will have 2 x 13 = 26 inches for a diameter.
The circumference of a circle with a diameter of 13 mm is: 40.84 mm
Circumference = pi*13 yards
The area of a circle with a diameter of 13 centimeters is: 132.7 cm2
The area of a circle with a 13 ft diameter is: 132.7 square feet.
The area of a circle, if it has a diameter of 13 feet, is: 132.7 square feet.
Area of circle (A) = Pi*r2 346.36 = Pi*r2 r2=346.36/Pi r=√(346.36/Pi) d=2r=2√(346.36/Pi) d ~= 21.000 yards
Well, area of a circle is (pi)r^2 and your diameter is 13, so your radius is 13/2 so your area would be (pi)(13/2)^2 or 132.7322896 =] -ray
The diameter of any circle is twice its radius. A circle with a radius of 13 inches will have 2 x 13 = 26 inches for a diameter.
The circumference of a circle with a diameter of 13 mm is: 40.84 mm
Area = pi*6.52 = 132.732 square feet to 3 decimal places
Well, darling, to find the area of a circle, you use the formula A = πr^2. Since the diameter is 26 feet, the radius is half of that, which is 13 feet. Plug that into the formula, and you get an area of approximately 530.66 square feet. Voila!
Diameter of circle: 13/pi = 4.138 ft to 3 decimal places
Diameter of circle: 13/pi = 4 mm rounded to the nearest integer
