How do you find the degree measure of a central angle in a circle if both the radius and the length of the intercepted arc are known?
-- Circumference of the circle = (pi) x (radius) -- length of the intercepted arc/circumference = degree measure of the central angle/360 degrees
What is the formula to find the circumference of a circle with the diameter given?
Circumference = (diameter) multiplied by (pi)
If a right triangle has 60 degree angle and a length of 8 meters how do you find the hypotenuse?
As the relationship between the length and angle given are unclear a graphic explanation can be found at the link below
How do you find the area of a circle without knowing the radius?
If the circumference or diameter is given then you can find the radius or simply measure the distance from the centre of the circle to the circumference.
What is the length of the side opposite the 30 degree angle?
It depends on the length of the other two sides which creates that angle. Not enough information was given. However, you can simply use the Cosine rule to find it if the other two lengths are known. a2=b2+c2- 2bccosA (A=30 and a is the length of the side opposite to 30 degree angle; b and c is the length of the sides which makes up the 30 degree angle)
How do you find length and width given the circumference?
If you mean the diameter and radius of a circle given the circumference it is:- diameter = circumference/pi radius = circumference/(2*pi)
How do you find the circumference of a circle that has an arc length and angle degree?
The total circumference is (arc length) times (360) divided by (the angle degrees)
How do you find circumference of cylinder given length and width?
The width times pi equals the circumference.
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.
How do you find the area if given the circumference of a circle?
Times length times width
How do you find the degree measure of a central angle in a circle if both the radius and the length of the intercepted arc are known?
-- Circumference of the circle = (pi) x (radius) -- length of the intercepted arc/circumference = degree measure of the central angle/360 degrees
How do you find the arc length when only given the degree and radius?
Length = angle˚/360˚ x 2∏r
Find the circumference of a circle with radius of inches (use 3.14for Pi)?
That will depend on the length of the radius which has not been given but in general the circumference of a circle = 2*pi*radius or diameter*pi
Which best describes how to find the length of an arc in a circle?
Divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
How do you find the degree of an arc with the given length?
say a circle's degree is 360. and cut it in half to make an ark. that would 180 degrees?
How do you find the radius when only the arc length and degree are given?
2*pi*r/Arc length = 360/Degreesince both are a ratio of the whole circle to the arc.Simplifying,r = 360*Arc Length/(2*pi*Degree) = 180*Arc Length/(pi*Degree)
How do you find the length of an arc in geometry?
length of arc/length of circumference = angle at centre/360 Rearranging the equation gives: length of arc = (angle at centre*length of circumference)/360
