The area of the sector formed by the 110 degree central angle is 40 units squared What is the radius of the circle?
measure of central angle/360 degrees = area of sector/area of circle 110 degrees/360 degrees = 40 unit2/ pi r2 unit2 11/36 = 40/pi r2 11 pi r2 = 40 x 36 11 pi r2 = 1,440 r2 = 1,440/11 pi r = square root of 1,440/11 pi r = 20.3 unit approximately
How do you find the angle with the radius and the arc length?
The arc length divided by the radius is the angle in radians. To convert radians to degrees, multiply by (180/pi).
If you only have the central angle of a circle can you find the radius?
If "the angle" means the angle between two radii at the centre, the answer is no. You need to know the circumference first. Then use radius = circumference divided by 2 x pi.
How would you convert an angle in degrees to angle in radians?
Divide the angle measured in degrees by (180/pi). Alternatively, multiply by (pi/180).
What is Pi divided by thirty two?
Pi divided by thirty two. .0981747704
What is the angle of an isoclese triangle divided by pi?
Any angle in degrees divided by pi is the value of the angle in radians , if that is what you are asking
What is the reference angle for -17pie divided by 6?
-23
Which angles are coterminal with 3pi2?
pi/2 is one possible answer.
How do you do coterminal angles with radian measure?
The same way as with degrees. All you have to know is how to convert degrees from radians and radians from degrees.... this is how you do it... radians= pi/180 degrees= 180/pi to get angles from degrees to radians you multiply the angle that is measured in degrees by pi/180. to get angles from radians to degrees you multiply the angle that is measured in radians by 180/pi. pi=3.14
Is 38 pi divided by 4 radians a quadrantal angle?
9.5
What kind of angle is 4 pi divided by 5?
pi = 180 degrees pi / 2 = 90 degrees 2 pi = 360 degrees so pi / 5 = 180 / 5 = 36 36 x 4 = 144 degrees a 144 degree angle is obtuse
What is the length of an arc of a circleof radius 8m if the central angle of the arc is 5 pi divided by 6?
It is (5*pi/6)*8 = 20*pi/3 m.
The area of the sector formed by the 110 degree central angle is 40 units squared What is the radius of the circle?
measure of central angle/360 degrees = area of sector/area of circle 110 degrees/360 degrees = 40 unit2/ pi r2 unit2 11/36 = 40/pi r2 11 pi r2 = 40 x 36 11 pi r2 = 1,440 r2 = 1,440/11 pi r = square root of 1,440/11 pi r = 20.3 unit approximately
What is the meaning of pi 3.14159265 ETC?
The constant pi is the ratio of the circumference of a circle divided by its diameter. In radians, it is also equal to an angle of 180 degrees.
How do you find the angle with the radius and the arc length?
The arc length divided by the radius is the angle in radians. To convert radians to degrees, multiply by (180/pi).
What are different kinds of angle differentiate each angle?
Acute angle in the range (0, pi/2) radians = (0, 90) degrees.Right angle = pi/2 radians = 90 degrees.Obtuse angle in the range (pi/2, pi) radians = (90, 180) degrees.Straight angle = pi radians = 180 degrees.Reflex angle in the range (pi, 2*pi) radians = (180, 360) degrees.Full turn = 2*pi radians = 360 degrees.
What Is pi divided into?
pi is not divided into anything - unless you specify pi/2 or pi/3.6
