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.
What is Pi divided by thirty two?
Pi divided by thirty two. .0981747704
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 the least positive angle co terminal with A pi divided by 6?
To find the least positive angle coterminal with ( \frac{\pi}{6} ), you can add or subtract multiples of ( 2\pi ). Since ( \frac{\pi}{6} ) is already a positive angle and less than ( 2\pi ), it is the least positive angle coterminal with itself. Therefore, the least positive angle coterminal with ( \frac{\pi}{6} ) is ( \frac{\pi}{6} ).
Coterminal with 3pi2?
To find an angle that is coterminal with ( \frac{3\pi}{2} ), you can add or subtract multiples of ( 2\pi ). For example, ( \frac{3\pi}{2} + 2\pi = \frac{3\pi}{2} + \frac{4\pi}{2} = \frac{7\pi}{2} ) is coterminal with ( \frac{3\pi}{2} ). Similarly, subtracting ( 2\pi ) gives ( \frac{3\pi}{2} - 2\pi = \frac{3\pi}{2} - \frac{4\pi}{2} = -\frac{\pi}{2} ), which is also coterminal.
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
Why are there an infinite number of angles that are co terminal to a certain angle?
There are an infinite number of angles that are coterminal with a given angle because coterminal angles differ by full rotations. Specifically, for any angle ( \theta ), you can find coterminal angles by adding or subtracting multiples of ( 360^\circ ) (or ( 2\pi ) radians). This means that ( \theta + 360^\circ n ) (where ( n ) is any integer) will always result in an angle that shares the same terminal side as ( \theta ), leading to an infinite set of such angles.
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.
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.
