This leads us to the rule to convert degree measure to radian measure. To convert from degrees to radians, multiply the degrees by π180° radians .
Multiply the number of degrees by π/180. Therefore, 1 degree is equivalent to (π/180) radians. Since you know this, all you have to do is multiply the number of degrees you’re working with by π/180 to convert it to radian terms.
From the latter, we obtain the equation 1 radian = (180π)o . This leads us to the rule to convert radian measure to degree measure. To convert from radians to degrees, multiply the radians by 180°π radians .
We need to first convert the given degrees(30°) in radians using the formula Radians = Degrees × π/180°. Radians = 30° × π/180° = π/6 rad. Hence, 30 degrees can be represented as π/6 rad.
Degree (a right angle is 90 degrees) and gradian measure (a right angle is 100 grads) have their uses. … The length of the arc subtended by the central angle becomes the radian measure of the angle. This keeps all the important numbers like the sine and cosine of the central angle, on the same scale.
- Radian measure = (π/ 180) × Degree measure.
- Degree measure = (180/π) x Radian measure.
The measure of an angle is determined by the amount of rotation from the initial side to the terminal side. One way to measure angles is in radians. … One radian is the measure of a central angle that intercepts an arc s equal in length to the radius r of the circle.
To convert to degrees, you multiply by 180/pi. But in most cases, you can find the measure of the angle by looking at a diagram or, if you’re talking about geometry, there’s different ways there to find the measures of the angles.
720 degrees, when converted to radians, is 4 radians. A complete circle is 360 degrees, which means that 720 degrees is : 720360=2 720 360 = 2 complete circles.

Explanation: Consider that π rad corresponds to 180° . So 45° is 180°4 or π4 .
So one radian is equal to 180π degrees, which is approximately 57.3∘.
Well, a Radian, simply put, is a unit of measure for angles that is based on the radius of a circle. … It is from this relationship that we say 2*π*r = 360 Degrees or that 1 Radian = 180/π Degrees and 1 Degree = π/180 Radians.
So one radian = 180/ PI degrees and one degree = PI /180 radians. Therefore to convert a certain number of degrees in to radians, multiply the number of degrees by PI /180 (for example, 90º = 90 × PI /180 radians = PI /2). To convert a certain number of radians into degrees, multiply the number of radians by 180/ PI .
Radian is another way of expressing the measure of an angle. One radian is equal to 57.2958. degrees. Complete step-by-step answer: Radian measure of a central angle of a circle is defined as the ratio of length of the arc subtended by that angle to the length of radius of the circle.
Degrees to radians: In geometry, both degree and radian represent the measure of an angle. One complete anticlockwise revolution can be represented by 2π (in radians) or 360° (in degrees). Therefore, degree and radian can be equated as: 2π = 360°
How do You Convert Radians to Degrees Minutes and Seconds? To convert radians to degrees, we divide by π and then multiply by 180. The fractions of a degree can be converted to minutes by multiplying the fraction by 60 to get the number of minutes.
210°=210/180*π radians = (7/6)π radians. The farmula which convert the degree into radian is that, 1°= π/180radian.
Therefore, to find 225° in radians, multiply 225° by π / 180. You’ll get 5π / 4, or 3.927 radians.

A measurement of 4 radians is equivalent to approximately 229 degrees.
So: multiply by 180 , then divide by π . To convert your problem, the answer would be 135∘ . Hope this helped!
Hi Jerry, It cannot be cleared as of now. It signifies “Radian”, a unit of measuring angles. Another one is “Degree” (if you tap “RAD” it will change to “DEG”).
andif you want to convert an angle from degree to radians: ar=αd⋅π180° . In our case: ar=315°⋅π180°=74π .
2π radians is equal to 360 degrees, meaning that one radian is equal to 180/π degrees. The relation can be derived using the formula for arc length.
