Since an entire circle is 2π radians, 1/8 would be π/4
Half circle plus quarter circle is equal to three-fourths of a circle. Three-fourths of a circle plus one eighth of a circle is seven-eighths. You still need one more eighth to complete the circle.

One revolution is 360 degrees or 2 pi radians ( full circle) So 13 rev = 13 x 60 degrees or 13 x 6.28 radians

A 1/4 of a circle is 90 degrees 1/8 of a circle is 45 degrees and they both add up to 135 degrees
By definition of the word, "revolution", there is only 1 revolution in a complete circle. You may be trying to ask a different question, such as how many radians are in one revolution. That answer is 2pi radians.
there are two Pi in a full circle so there is only one Pi in one radian.
There are 45 degrees in an octant because an octant is 1 eighth of a circle, and a circle is 360 degrees, and 45 degrees is one eighth of 360.
One eighth of a circle.
One eighth of a circle.

A full circle is 360 degrees. One eight of a full circle is 360/8 = 45 degrees
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.
One way to remember it is: a full circle is 2pi radians, or 360°, so 2pi radians = 360°, and then you multiply degrees by (2pi/360 radians per degree) = pi/180 radians per degree.
If the 49.5 is in radians, then sin 49.5 ≈ −0.693 and so yes. If the 49.5 is in degrees, then sin 49.5o ≈ 0.760 If the 49.5 is in gradians, then sin 49.5 ≈ 0.702 If the 49.5 is in some other angle measurement, then you'll have to decide as I only know Degrees, Radians and Gradians angle measures. In Degrees, one full turn is 360o In Radians, one full turn is 2π radians ≈ 6.283 radians In Gradians, one full turn is 400 gradians. Radians are most useful in calculus. In fact you've used radians without realising it: The length of an arc of angle θ of a circle of radius r is θr when θ is measured in radians; the length of an arc of a circle round one full turn (ie the circumference of a circle) is θr = 2πr since one full turn is 2π in radians.

No. The Diameter is the length from one end to the next. The radius is half of that.
