I guess you are referring to a circle with area 120 m2 and want to know its radius: area_circle = π x radius2 ⇒ radius = √(area_circle ÷ π) = √(120 m2÷ π) ≈ 6.18 m
120 degrees because there are 720 degrees interior angles in an hexagon.
A 120 degree angle is an obtuse angle. This means that the angle is between 90 and 180 degrees.
circumference = 2*pi*7 = 43.98229715 arc = (120/360)*43.98229715 = 14.66076572 or 14.661 units rounded to 3 dp
Length of arc = pi*radius*angle/180 = 10.47 units (to 2 dp)
The radius of a circle has no bearing on the angular measure of the arc: the radius can have any positive value.
It will be 1/3 of the circle's circumference
To find the radius of a circle from a central angle of 120 degrees, you need additional information, such as the length of the arc or the area of the sector. If you have the arc length (s), you can use the formula ( r = \frac{s}{\theta} ), where ( \theta ) is in radians (120 degrees is ( \frac{2\pi}{3} ) radians). If you know the area of the sector, you can use ( r = \sqrt{\frac{A}{\frac{1}{2} \theta}} ), where ( A ) is the area and ( \theta ) is in radians. Without extra data, the radius cannot be determined solely from the angle.
An arc length of 120 degrees is 1/3 of the circumference of a circle
circumference of the circle = 2*pi*10 = 20pi units of measurement length of arc = (120/360)*20pi = 20.944 units (rounded to 3 decimal places)
The length of an arc, with an angle in degrees, is equal to (pi x r x θ)/180.In this case, it is (pi x 120 x 10)/180, which is (20pi)/3 or about 20.944.This answer is not right for A+

A whole circle is 360 deg so the major arc is 360-120 = 240 degrees.
The interior angles of a regular hexagon measure 120° A regular hexagon has all sides the same length and all angles are equal.
