Hold it right there. That's not possible. Something's gotta give.
The area of a circle = pi R2 = pi (half the diameter)2
If the circle has a diameter of 16, then its area is 201.1(rounded).
If it has an area of 64, then its diameter is 9.03(rounded).
If it has a diameter of 16 and an area of 64, then it's not a circle.
Area of a Circle = Pi * radius squared Radius = Diameter / 2 So, Area = Pi * (16/2)^2 = Pi * 64 = 201.06 m^2 Measurement is in meters squared.
Area of a circle = pi R2R = radius = 1/2 diameter.For diameter = 16 inches, Area = pi (8)2 = 64 pi = 201.1 square inches (rounded)
area/pi = diameter 200.96/pi = 63.96755473 or 64 units in length.
The circumference of the circle with a diameter of 64 mm is 64*pi = about 201 mm
Area of a circle = pi (radius)2Radius = 1/2 of the diameterArea of your circle = pi (4)2 = 16 pi = 50.265square feet
Using 3.14 as Pi the area of circle is: 200.96
If the area of a circle is 64 square units the diameter is: 9.027 units.
Area = pi * radius * radius radius = diameter / 2 radius = 16/2 = 8 Area = 64 * pi Area 201.062 inches2
Formula for finding the area of a circle: Area = pi * r2 a = 3.14 * 82 a = 3.14 * 64 a = 201.06
The diameter = 2*r where r is the radius of the circle. So 16 = 2r. Therefore the radius = 16/2 = 8. The area of a circle = Pi*r^2 = Pi*(8)^2 = 64*Pi.
Area of a Circle = Pi * radius squared Radius = Diameter / 2 So, Area = Pi * (16/2)^2 = Pi * 64 = 201.06 m^2 Measurement is in meters squared.
In this case, the radius is easiest calculated from the diameter. The radius is simply half the diameter.
Divide the diameter by 2 to get the radius. Then use the formula for the area of a circle: area = pi x radius2.
Area of a circle is pi r^2 diameter is twice the radius. 3.14*8*8=64*pi or approximately 200.96
Area of a circle = pi R2R = radius = 1/2 diameter.For diameter = 16 inches, Area = pi (8)2 = 64 pi = 201.1 square inches (rounded)
That will depend on whether the 64 inches is the radius, diameter, or circumference of the circle.
The area of a circle is worked out using the formula: area = Pi x (radius x radius) (a.k.a Pi r2 <- sorry, no Pi symbol available. ) The diameter is always twice the radius (the radius is the distance from the edge of the circle to the centre, the diameter is the distance from one edge to the other, through the centre). So, if your circle has a diameter of 16 feet, the radius will be 8 feet. Area = Pi x 82. = Pi x 64. Pi = 3.14159 So... Area = 3.14159 x 64 = 201.1 feet2.
