The radius of the sector with an angle of 27 degrees and arc of 12cm is: 25.46 cm
How do you convert degree of rotation into mm?
Degrees of rotation does not convert directly to millimeters so the question in its current form has no answer. However, if the question is, "Given a known radius measured in millimeters and given a known angle in radians how do you find the length of the arc formed?" then the answer is: s = rθ Where s = the length of the arc r = the radius in question θ = the known angle Example radius = 20mm θ = 0.52 radians (30 degrees) s = (20)*(0.52) = 10.47mm If your θ is in degrees then the formula s = rθ will look like this: s = rθ*pi/180
Im making a conical frustum. i need to know how to get the dimensions so i can cut out a shape to wrap around the frame i have built. any ideas?
Start with a circle of radius equal to the height of a right cone that would be the extension of your frustum. Measure or calculate from the bottom of the frustum up the side and subtract that from the first radius. This remainder is a radius to form a smaller circle concentric with the first one. Now determine the length around the top and bottom of the frustum. This will correspond to a number of degrees within your circles. Draw this angle from the center to the edge of the outer circle. Now cut out the small circle and then the angle section. This should roll into the shape you want. If you use paper for this, be mindful of the grain of the paper. Poster board only rolls in one direction.
What is the meaning of general drill bit angle?
It is the angle between the cutting edges.It is usually 118 degrees
Definition of solid angle?
solid angle is the ratio of the intercepted area dA of the spherical surface , described about the apex O as the centre ,to square of its radius r
What is the radius of the sector with an angle of 27 degrees and arc of 12cm?
The radius of the sector with an angle of 27 degrees and arc of 12cm is: 25.46 cm
If a sector has an angle of 118.7 and an arc length of 58.95mm what is its radius?
If a sector has an angle of 118.7 and an arc length of 58.95 mm its radius is: 28.45 mm
How do you find the radius of a circle if the central angle is 36 degrees and the arc length of the sector is 2 pi cm?
The measure of the central angle divided by 360 degrees equals the arc length divided by circumference. So 36 degrees divided by 360 degrees equals 2pi cm/ 2pi*radius. 1/10=1/radius. Radius=10 cm.
How do you find the length of a sector?
The answer depends on what information you do have: radius, arc length, central angle etc.
Calculate a sector of a circle if the angle is 150 degrees and the radius is 13cm?
The area of the sector is: 221.2 cm2
How do i find the arc length if i know the area?
Use the formula for the area of a circular sector, and solve for the angle.For a circular sector: area = radius squared times angle / 2 (Note: The angle is supposed to be expressed in radians; and in this specific problem, there is no need to convert it to degrees.) Since you know the area and the radius (according to the comments added to this question), you can solve for the angle. Once you know the angle (in radians!), the arc length is simply angle x radius.
What is the area of the shaded sector if the circle has a radius of 3 and the central angle is 90 degrees?
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
How do you calculate the the arc of a sector?
To calculate the arc length of a sector: calculate the circumference length, using (pi * diameter), then multiply by (sector angle / 360 degrees) so : (pi * diameter) * (sector angle / 360) = arc length
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).
What is the length of the minor arc if the angle is 30 degrees?
It's 0.524 of the length of the radius.
What is the length of an arc with a radius of 5 and the central angle is 120 degrees?
Length of arc = pi*radius*angle/180 = 10.47 units (to 2 dp)
What is the area of the shaded sector with a radius of 7?
That will depend on the length or angle of the arc which has not been given
