The answer depends on how long will it take for WHAT!
In order to find radians, you simply have to put Arc Length over Radius. Radius = 20 Arc Length = 45 45/20 = radians radians = 2.25
The answer is undefined as the Cotangent of Pi is undefined.
If traveling at 30,000,000 mph over a radius of 151.045/2 = 75,522.5 miles the rotational velocity is 30000000/75522.5 = 397.23 radians per hour. Since a rotation is 2 pi radians, that is 63.22 revolutions per hour, or 0.0176 rotations per second
You don't need to "get over" him. You guys can have a long-distance relationship!
The cosine of 0.489957 radians is 15/17
Since angular acceleration is in radians per second squared, which is change in angular speed over time, we know that α=ω/t, where α is angular acceleration, ω is angular speed, and t is time (assuming α is constant.)ω is measured in radians per second. If me multiply ω by r, which is the radius of the circle the object is acceleration around, we get ωr, which has units of (radians*radius)/second. Since the angle in radians times the radius gives the distance, these units are equivalent to meters/second, so ωr = v.Therefore, α=(v/r)/t=v/rt.Acceleration (a) is v/t, so α=(v/t)(1/r)=a/r.The equation would then be:α=a/r, or a=rα (Where α is angular acceleration, a is acceleration, and r is the radius.)
The answer will depend on whether the angles are measured in degrees or radians. That information is not provided and so the question cannot be answered.
You can calculate that on any scientific calculator. Presumably, for any expression that involves "pi" the angle should be in radians, so be sure to set the calculator to radians first.
I guess you mean 3 pi over 2, ie 3π/2 though it may have been given to you as (3/2)π To solve this, find the total angle turned in 60 seconds and divide by the angle in a whole turn, ie one revolution. In 60 seconds it will turn through an angle of 60 × 3π/2 radians = 90π radians One revolution is 2π radians → 90π radians = 90π/2π revolutions = 45 revolutions (45 rpm - the figure calculated - was the standard for a single).
A major arc must measure over 180 degrees, or pi radians
A place on a mountain roadway where slower moving vehicles can pull over is called a turnout. These are typically long enough that the slower vehicle can pull over but not have to stop.
If an arc of a circle is drawn so that the length of the arc is equal to the radius of the circle then the angle at the centre of the circle subtended by the arc is called one radian.Then the angle subtended by the entire circle is given by the ratio , circumference / radius = 2πr/r = 2π radians.2π radians is equivalent to 360°So, π radians = 180°and thus, π/2 radians = 90°Pi over two, or Pi divided by two radians is the name for 90° in a circle.
