Area = pi * radius^2. radius = diameter / 2, so radius of this circle is 3.Area = 9 * pi (take your favorite value of pi: 3.1416....)
Circumference of circle: 20 × π = 62.832 feet rounded to 3 decimal places
Using 3.14 as Pi the area of circle is: 28.259999999999998
The formula for the area (A) of a circle is A = π r2 - where r is the radius. The diameter (d) of a circle is twice the radius. The area of circle having a diameter of 24 ft is A = π 122 = 144π = 452.39 sq ft (2dp)
The circumference of a circle with an area of 3 acres is: 1,281 feet.
Area = pi * radius^2. radius = diameter / 2, so radius of this circle is 3.Area = 9 * pi (take your favorite value of pi: 3.1416....)
A 12-inch circle has an area of 0.784 square feet.
Zero. Circles have area, but no volume.
The area of a 3 cm circle is: 7.069 square cm
Circumference of circle: 20 × π = 62.832 feet rounded to 3 decimal places
Area of a circle = pi x radius squared. The radius of a circle is equal to half the diameter, in this case 600/2 = 300mm. So area = pi x 3002 = 282743 mm2 (nearest mm2)
The area of a 3 cm circle is: 7.069 cm2
Using 3.14 as Pi the area of circle is: 28.259999999999998
The formula for the area (A) of a circle is A = π r2 - where r is the radius. The diameter (d) of a circle is twice the radius. The area of circle having a diameter of 24 ft is A = π 122 = 144π = 452.39 sq ft (2dp)
The circumference of a circle with an area of 3 acres is: 1,281 feet.
The area of a circle that has diameter of 3 cm is: 7.069 cm2
