The ratio of a circle's circumference to its diameter is a constant but irrational (meaning its precise value cannot be fully written out using traditional numbers) number called Pi (π). Pi ~= 3.1415927 Circumference = Pi (3.1415927...) * Diameter (120 inches) ~= 376.991118 inches ~= 377 inches
Never heard of centermetres before, and an area cannot be 120 centimetres because that is a measure of distance, not area. Instead, let us start with an area of 120 SQUARE centimetres. For a given area, the shape with the smallest perimeter is a circle. A circle with an area of 120 sq cm would have a radius of 6.18 cm and so a perimeter of 38.83 cm (to 2 dp).

To find the square footage of a circle with a 120-foot diameter, you first need to calculate the radius by dividing the diameter by 2 (120 feet ÷ 2 = 60 feet). The formula to find the area of a circle is A = πr^2, where A is the area, π is a constant approximately equal to 3.14159, and r is the radius. Plugging in the values, the area of the circle is A = 3.14159 x (60 feet)^2 ≈ 11,309.73 square feet.
Diameter of the circle: 120/pi = 38.197 inches rounded
Oh, dude, you just gotta divide the diameter by 2 to get the radius, which is 120 mm. Then you square that bad boy to get 14,400 mm². So, like, the area of the circle is 14,400 mm². Easy peasy, lemon squeezy.
Since diameter is twice its radius, the radius of this circle would be 60
Circumference equals pi multiplied by diameter. Therefore 120 (circumference) divided by pi equals diameter. Pi is on your calculator.

Area of whole circle = pi*r2 = 64*pi Area of Sector = Area of Whole Circle * Angle of Sector/Angle of Whole Circle = Area of Whole Circle * 120/360 = Area of Whole Circle / 3 = 64*pi/3 = 67.0 to the nearest tenth.

The area of a sector in a circle if the radius is 4 cm and the arc has degree 120 is: 16.76 cm2
if a circle has a radius of 12cm and a sector defined by a 120 degree arc what is the area of the sector
