What is the length of an arc with a radius of 5 and the central angle is 120 degrees?
Length of arc = pi*radius*angle/180 = 10.47 units (to 2 dp)
What is the length of the arc formed by central angle 2x?
If the angle is 2x radians then the length of the arc is 2x*r units where the radius of curvature is r units. If you measure the angle in degrees, then the length of the arc is pi*x*r/90 units.
What is the length of the miror arc with an angle of 82 degrees?
radius*82*pi/180 units. radius*82*pi/180 units. radius*82*pi/180 units. radius*82*pi/180 units.
How do you draw a line 12 long at a 22.5 degree angle?
Draw a circle with radius of 12 units and draw the horizontal diameter. Draw the perpendicular bisector for this line. Bisect the angle that is formed above the horizontal line. Again, bisect the angle that is formed above the horizontal line: extend this line to the circumference of the circle. This line will be 12 units long because it is a radius of the circle. It is a quarter (half of half) of the 90 degree angle and so the incline is 22.5 degrees.
What is the area of a sector with a central angle of 32 and a radius of 8.5?
Area of sector = (32*pi*8.52)/360 = 20.18 square units correct to 2 dp
The area of a sector formed by a 110 degree central angle is 50 units what is its radius?
45.33

its 45.33 :)..people just need to get straight to the freaking point!

Length of arc = pi*radius*angle/180 = 10.47 units (to 2 dp)
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.
What is the length of the arc formed by central angle 2x?
If the angle is 2x radians then the length of the arc is 2x*r units where the radius of curvature is r units. If you measure the angle in degrees, then the length of the arc is pi*x*r/90 units.
What is a area of a sector formed by central angles 2x?
2x*r2 square units where r is the radius and 2x is the angle (measured in radians).
What is the length of the miror arc with an angle of 82 degrees?
radius*82*pi/180 units. radius*82*pi/180 units. radius*82*pi/180 units. radius*82*pi/180 units.
What is the area of the shaded sector with a central angle of 260 and radius of 12?
Area = pi*122 = 144pi square units Shaded area = (260/360)*144pi = 104pi square units

Why is the answer for arc length in units and not in square units?
Because it is still length. It is measured along a curve (arc), rather than a straight line. It can be found by multiplying the arc angle (in radians) by the radius. So a complete circle has an angle of 2*pi radians. Multiply this by the radius and you have 2*pi*radius, which is the circumference of a circle (measured in units, not square units).
