Circumference equals pi multiplied by diameter. Therefore 120 (circumference) divided by pi equals diameter. Pi is on your calculator.
Divide the circumference by the value of Pi and divide the result by 2 - that will give you your answer.
Assuming you know the location of the center of the circle, to divide a circle into thirds, do the following:mark a point on the circumference and, using a protractor, mark 120 degreesthen repeat for the final markA line from the mark on the circumference to the center will show an angle of 120 degrees.
radius = 120/(2*pi) = 19.09859317 cm area = pi*19.098593172 = 1145.91559 or about 1146 square cm
120 inch pounds = 10 foot pounds.
There 12 inches to a foot, so 120 tenths of an inch to a foot.
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
Diameter of the circle: 120/pi = 38.197 inches rounded
Construct a circle with a 4.5 radius. The circle's circumference is 360 degrees. So mark out 3 by 120 degrees on the circumference and join them to the centre of the circle which will divide the circle into three equal parts.
Circumference = pi ( 3.1416, a constant) * diameter = 3.1416 * 38.2 = 120 sq. units
360 degrees in a circle 120 degrees = 12mm 360 degrees = 36mm Therefore the circumference of the circle is 36mm.
Since diameter is twice its radius, the radius of this circle would be 60
A central angle of 120 is one third of the circle, so the arc length of 28.61 is one third of the circumference. 28.61 X 3 = 85.83
Circumference will be 120 pi inches, ie 31 feet and very nearly 5 inches
First we have to find the radius: pi*radius2 = 120 sq ins Divide both sides by pi and then square root both sides: radius = 6.180387232 inches circumference = 2*pi*radius circumference = 38.83251825 or 39 inches to the nearest inch.
Estimate: 3*40 = 120 inches Actual: pi*39 = 122.5 inches to one decimal place
Divide the circumference by the value of Pi and divide the result by 2 - that will give you your answer.
