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)
2.82 metres
Its circumference = 600*pi mm
The perimeter of a circle is called the circumference. Its formula is C = pi x diameter. The value of pi is often rounded to 3.14 for problem solving purposes. So just plug in the values for pi and the diameter into the formula to get the circumference of the circle: 3.14 x 600mm = approximately 1884 mm.
You would first start by dividing the diameter by two to get the radius. This provides a radius of 1.375 inches. The formula for the area of a circle is pi*radius^2. So 1.375^2 = 1.891. This answer multiplied by pi gives a final area of 5.94 square inches.
circomference of a circle = pi*diameter = pi*14
600mm x 600mm is 0.36m2.
Its circumference = 600*pi mm
The area is 7.068 units2
A 12-inch circle has an area of 0.784 square feet.
Zero. Circles have area, but no volume.
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....)
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)
Divide the diameter by 2 to get the radius. Then use the formula: area = pi x radius2.
It is: 10*pi
The perimeter of a circle is called the circumference. Its formula is C = pi x diameter. The value of pi is often rounded to 3.14 for problem solving purposes. So just plug in the values for pi and the diameter into the formula to get the circumference of the circle: 3.14 x 600mm = approximately 1884 mm.
It is: 600mm = 60cm
Area of a circle is pi*(radius)². Pi is a dimensionless constant (approximately 3.14). Radius is 1/2 of the diameter, so if you replace radius with diameter/2, then you get (3.14)*(dia/2)² = (3.14/4)*(dia)², or approx. (0.785)*(diameter)²
600mm = 60cm
