How do you find radius of a circle if given arc length?
you will need to know the angle subtended by the arc; arc length = radius x angle in radians
How do you find the arc length with the angle given?
An arc can be measured either in degree or in unit length. An arc is a portion of the circumference of the circle which is determined by the size of its corresponding central angle. We create a proportion that compares the arc to the whole circle first in degree measure and then in unit length. (measure of central angle/360 degrees) = (arc length/circumference) arc length = (measure of central angle/360 degrees)(circumference) But, maybe the angle that determines the arc in your problem is not a central angle. In such a case, find the arc measure in degree, and then write the proportion to find the arc length.
A supplementary angle to a 31 degree angle has a measure of what degree?
180-31=149 149 degree angle
What is radian measure?
A unit of angular measure equal to the angle subtended at the center of a circle by an arc equal in length to the radius of the circle, approximately 57°17'44.6"
The measure of the first angle of a triangle is 48 degree.the measure of the second angle is 32 degree .what is the measure in degrees of the third angle?
100.
How do you find an arc measure?
It depends on what measure you want: the angle subtended or the length of the curved segment, and also on what information you do have.
How do you find chord with known radius and degree?
Length of chord (assuming that is what you want) = 2*r*sin(x/2) where x is the measure of the angle subtended at the centre.
Find the measure of arc DB?
A+ = 82. * * * * * It depends on what measure you want: the angle subtended or the length of the curved segment, and also on what information you do have.
What is the difference between the measure of an arc and arc length?
They are normally the same. However, the measure of the arc could refer to the angle subtended at the centre of the radius of curvature.
How do you find radius when arc length is given?
Let us recall the formula for the circumference of a circle. That one is 2pi r. r is the radius of the circle and 2pi is the angle in radian measure subtended by the entire circle at the centre. If this is so, then any arc length 'l' will be equal to the product of the angle in radian measure subtended by the arc at the centre and the radius.So l = theta r. Say theta is the angle subtended by the arc at the centre.Therefrom, r = l / Theta.
What is the value of the degree of an angle in a semi-circle?
An angle subtended at the semicircular arc is 90 degrees.
How do you find the side of a triangle?
To find the degree of angle of a side of a triangle, a protractor is needed to measure the angle. Place the '0' on the protractor on the point of the angle and look at the top part to determine degree of angle. To measure the length of a triangle side, a simple ruler can be used to measure the length.

How can you angle expressed in degree into millimeter?
Millimetres measure length, degrees measure angle, therefore you cannot change one into the other.

An angle subtended by an arc is double at the center?
an angle subtended by an arc is double at the center
What is the unit used to measure distances around a circle?
Radian is the unit used to measure distances around a circle. It is defined as the angle subtended at the center of a circle by an arc equal in length to the radius of the circle.
