Circumference is pye times twice the radius or by the diameter
3.1417 X 6 ( diameter or 2 times the radius )= 18.8496
90 degrees is 1/4 of the circumference
18.8496 divided by 4 = 4.7124 cms
arc of 90 degrees =4.74124 cms

How will I determine the radius of gyration using bifilar suspension?

To determine the radius of gyration of given bar using bifilar suspensionmethod.
Uniform steel bar, cylindrical weights, stop watch.
Fig 1 shows the general arrangement for carrying out experiment. A
uniform rectangular section bar is suspended from support frame by twoparallel cords.

Two small chucks fitted in the frame and other endssecured in bifilar bar. Ends of these cords pass through a chuck so as tofacilitate for change in length of the cord it is possible to adjust length of chord by loosening the chuck.The suspension may also be used to determine radius of gyrationof any body,In this case the body under investigation is bolted to thecenter. Radius of gyration of combined bar and body is then determined.
1) Suspend the bar from chuck and adjust length of chord ' L' convenientlynote the suspension length of each cord must be same.2) Allow the bar to oscillate about the vertical axis passing through center of gravity and measure periodic time 'T' by knowing time for 20oscillations.3) Repeat the experiment by mounting the weights one equal distancefrom the center.
Consider bar AB whose moment of inertia is to be determine issuspended by two parallel strings as shown in figure 2.Let, L = length of each string.m = mass of bar.K = radius of gyration about the vertical axis through G.I = mass moment of inertia about the vertical axis through G.2r = distance between two stringsT = tension in each string
= angle of twist of bar.
= angle of twist of string
= angular accelaration of the bar.Initial position of bar is AGB. Now, if bar is set gently in vibration inhorizontal plane, it will start oscillating about vertical axis through its masscenter G. when bar is twisted about its C.G, through an angle
, bar is inposition A'GB' as shown. When bar is getting
as angular displacement,then string is getting
as angular displacement about vertical, distancemoved by point A is arc AA'
arc AA' = r

= r

What's the measure of an arc if it's central angle is 35 degrees?

Assume the central angle is 35 degrees and the radius is 1.

The circumference of the whole circle is 2 x pi x radius. Since the radius is 1, the circumference will be 2 x pi.

Now a full circle is 360 degrees.

Now we can set up a ratio of 35 degrees is to 360 degree as x is to 2pi.

35 x
---- = -------
360 2xpi

Cross-multiply and isolate your variable.

Good luck.

How to find the length ot the arc ,a circle has a radius of 45cm.

You can not do it unless you know the measure of the central angle sustending (supporting) the arc. If the angle is known, you use the proportionality relation that follows:
If angle is in degrees
(length of arc) / circumference=(measure of central angle sustending arc)/360.
Here the circumference is 2*PI*radius.

If angle is in radians , the relation is somewhat simpler,
arc length= (radius length)* (angle measure in radians)
It is clear that in the last relation, the unit for the arc length is the same as the unit for the radius.

A pizza is divided into 8 equal parts. what is the area of one slice if its radius is 6 inches?

Hello and Welcome to FixYa!
Area of pizza (Combined Bread + Crust) = Area=pie * (radius)^2. If divided in 8 equal parts, Area of 1 piece=Area/8.
Area= 3.1415* (0.1524)^2 Area of 1 slice= Area/8 Concerned.

Find the radius of a circle in which a 40o central angle cuts off an arc whose length is 4pi

If an arc is 4╥, it is 12.56.
You can use 12.56 as a starting point and figure out what circumference that is 40° of.

Circumference = 2 • π • radius = π • diameter

Reverse this and you will have your answer.

A 30o angle cuts off an arc in a circle with a diameter of 10 in. Find the length of the arc to the nearest hundredth.

The arc length can be obtained by:

(pi x r x Angle) / 180


(3.1415 x 5 x 30) / 180 = 2.618 in.

Hope this helps...
