To find the diameter of a circle with a given circumference, you can use the formula: circumference = π * diameter. Given the circumference of 120 inches, you can plug this into the formula: 120 = π * diameter. Solving for diameter, you get diameter = 120 / π ≈ 38.2 inches.
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.
