If a piece of wire 40 cm long is bent into a arc of a circle subtending an angle of 60 degree at the center, then what is the radius of the circle?
Circumference of the circle formed after extrapolating the section is 40cm × 6 because 60 degrees × 6 = 360 degrees (making one circle) = 240 cm This circle circumference = 2×pie×radius = 240 cm Therefore radius = ( 120/pie )cm.
A uniform wire of length 20cm is bent into shape V of 60 degree. What is distance of its center of mass from vertex A?
A copper wire when bent in the form of a hexagon encloses an area of 726*Sqrt(3) cm^2. If the wire is bent to form a circle, find the area enclosed by it.
If O is the center of the circle in the figure. Find, in degrees Angle QPR + Angle ORQ = ??
The arc, centered at point O, is a quarter-circle. Find the simplest formula for the radius of the circle in terms of a, b, and c.
