What is the circumference of the circle The length of arc AB is 28.61?
To find the circumference of the circle when the length of arc AB is given, we also need to know the angle subtended by the arc at the center of the circle. The formula for the length of an arc is ( L = \frac{\theta}{360} \times C ), where ( L ) is the arc length, ( \theta ) is the angle in degrees, and ( C ) is the circumference. Without the angle, we cannot directly calculate the circumference. If you provide the angle, I can help you find the circumference.
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)
What is the arc length if the length of the arc is 95 degrees?
Find the circumference of the whole circle and then multiply that length by 95/360.
What is the circumference if the arc length is 19.68?
To find the circumference of a circle when given the arc length, you need to know the angle in radians that corresponds to that arc length. The formula for arc length is ( L = r \theta ), where ( L ) is the arc length, ( r ) is the radius, and ( \theta ) is the angle in radians. If the arc length of 19.68 represents a complete circle (360 degrees or ( 2\pi ) radians), then the circumference would be ( 19.68 ). If it represents a fraction of the circle, additional information about the angle is needed to calculate the total circumference.
How do you find the length of the arc in a semi circle when its radius is given?
To find the length of the arc of a semicircle, use the formula ( L = \pi r ), where ( r ) is the radius of the semicircle. Since a semicircle is half of a full circle, the total circumference of a circle is ( 2\pi r ), and the length of the arc for the semicircle is half of that. Simply multiply the radius by ( \pi ) to get the arc length.
To find arc length what do you need to multiply a circle's circumference by?
the fraction of the circle covered by the arc
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)
What is the arc length if the length of the arc is 95 degrees?
Find the circumference of the whole circle and then multiply that length by 95/360.
How do you find the arc length of a minor arc when c equals 18.84?
I'm assuming that "c" is short for "circumference". The length of an arc is (circumference)*(360/angle). So the length of an arc in a circle with circumference length of 18.84 is 6782.4/angle, where the angle is measured in degrees.
What is the circumference if the arc length is 19.68?
To find the circumference of a circle when given the arc length, you need to know the angle in radians that corresponds to that arc length. The formula for arc length is ( L = r \theta ), where ( L ) is the arc length, ( r ) is the radius, and ( \theta ) is the angle in radians. If the arc length of 19.68 represents a complete circle (360 degrees or ( 2\pi ) radians), then the circumference would be ( 19.68 ). If it represents a fraction of the circle, additional information about the angle is needed to calculate the total circumference.
What is arc length?
It is part of the circumference of a circle
How do you find the arc ABC length 120 degrees 10?
An arc length of 120 degrees is 1/3 of the circumference of a circle
How would your find the fraction of a circle that an arc covers?
Use the information you have to find it. -- divide the length of the arc by the total circumference of the circle, or -- divide the central angle of the arc by 360 degrees (a full circle)
If the circumference of the circle is 32 cm what is the length of the thick arc that covers one-quarter of the circle?
If the circumference of the circle is 32 cm, the length of the arc that is 1/4 of the circle is: 8 cm
What is the arc in a circle that is 90 degrees?
To find the arc length, you also need to know the radius (or diameter) of the arc. The arc length is then found by finding the circumference of the full circle (2xPIxradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
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 length of the arc of a circle with only the measurement of the central angle and the Circumference?
The entire circumference has a central angle of 360 degrees. The arc is a fraction of the circumference. The fraction is (central angle) divided by (360). So the arc length is: (circumference) x (central angle) / (360) .
