If An ARC measures 120 degrees what is the length of the radius of the circle?
The radius of a circle has no bearing on the angular measure of the arc: the radius can have any positive value.
How do you find a radius of a circle 120 degrees?
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.
How do you divide a circle with 9cm diameter in three equal parts?
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.
If a 120 degree arc is 12mm long what is the circumference of the whole circle?
360 degrees in a circle 120 degrees = 12mm 360 degrees = 36mm Therefore the circumference of the circle is 36mm.
What is it which a circle divides into 3 parts?
360 ÷ 3 = 120 degrees Therefore the circle (360 degrees) has been split into 3 parts of 120 degrees each.
Find the area of a 120 degree sector of a circle with a radius of 6?
There are 360 degrees in a circle so it will be 1/3 of pi*62 square units
If An ARC measures 120 degrees what is the length of the radius of the circle?
The radius of a circle has no bearing on the angular measure of the arc: the radius can have any positive value.
Find the area of a sector in a circle if the radius is 4 cm and the arc has degree 120?
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 12 cm and a sector defined by a 120 degree arc what is the area of the sector?
if a circle has a radius of 12cm and a sector defined by a 120 degree arc what is the area of the sector

A central angle measuring 120 degrees intercepts an arc in a circle whose radius is 6. What is the area of the sector of the circle formed by this central angle?
The area of the sector of the circle formed by the central angle is: 37.7 square units.
If the Diameter of a circle is 120 what is the radius?
Since diameter is twice its radius, the radius of this circle would be 60
What is the area of the sector formed by central angle of 120 degrees and a radius of 5?
A central angle of 120 is 1/3 of the total circle. Aea of a circle = pi x r2, so for this sector the area is (1/3)pi x r2 = (1/3)(3.14)(52) = 26.17
What is the area of a circle with a circumference of 120 cm?
radius = 120/(2*pi) = 19.09859317 cm area = pi*19.098593172 = 1145.91559 or about 1146 square cm
What the radius of 120m squared.?
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
What is area to the nearest tenth of a 120 degree sector of a circle with radius of 8 ft?
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.
