What is the length of arc AB if the central angle is 120 degrees and the radius is 10?
circumference of the circle = 2*pi*10 = 20pi units of measurement length of arc = (120/360)*20pi = 20.944 units (rounded to 3 decimal places)
If a (7 9) and b (3 12) what is the length of ab?
Using the distance formula the length of ab is 5 units
Point D is the center of the given circle What is the measure of ab?
96 TM!!!
Is the ratio of the length of the opposite leg to the length of the adjacent leg?
Suppose ABC is a triangle. There is nothing in the question that requires the triangle to be right angled. Suppose AB is the side opposite to angle C and BC is a side adjacent to angle C. Then AB/BC = sin(C)/sin(A)
If a(-1-3)and b(11-8)what is the length of ab?
If you mean endpoints (-1, -3) and (11, -8) then by using the distance formula the length between the points is 13 units
A diagram shows a circle with center O. Given that the length of the major arc AB is 42 cm what is the length in cm of the radius?
length work
The length of arc AB the minor arc is 40 cm what is the circumference of circle C?
All you've told us is that 40 cm is less than 1/2 of the circumference. With that information, all we know is that the circumference is more than 80 cm. We could calculate it if we knew what the angle is at the center of circle between the two radii (radiuses) that go to the ends of arc AB. We're guessing that it's there in your book, but you forgot to include it when you decided to ask us to do your homework problem for you.
If ab measures 160 what is the length of the radius of this circle?
In order to answer that question, we'd need to see the drawing, and find out how 'ab' is related to the circle.
If ab measures 135 what is the length of the radius of this circle?
3.82 units
What is the length of arc AB if the central angle is 120 degrees and the radius is 10?
circumference of the circle = 2*pi*10 = 20pi units of measurement length of arc = (120/360)*20pi = 20.944 units (rounded to 3 decimal places)
Points A and B are distinct points that lie on the circumference of a circle with center C such that the measure of minor arc AB is 80 degrees. How many points on the circumference of the circle are e?
exactly three times as far from point A as they are from point B?
In circle O the area of the sector with central angle AOB is 30 pi cm squared and radius OA is 6 cm. What is the angle measure of arc AB and the length of AB?
The area of the whole circle is PI x 6 squared which equals 36 PI. We can now use the ratio 30/36 = x/360 to find the angle (360 is the full angle if the circle, x is the angle of the segment, pi's cancell out) If we solve for x we get 300 degrees which is the angle we need. As for the length, the circles circumference is 12 PI (12 is the diameter). This means that 30/36= AB/12PI AB=10PI
What is the measure of arc ACB if the circumference is 240 in and arc AB is 40 in?
Arc AB represents 40/240 = 1/6 of the circumference of the circle. As the angle at the centre subtended by the whole circle is 360° then ∠A0B (if the center is O) measures 1/6 x 360 = 60°. Since a central angle has the same number of degrees as the arc it intercepts, the arc ACB (note we can call the arc AB as arc ACB) measures 60°.
AB is a chord of a circle of radius 4.3 cm and P is a point on it which divides it into two parts in the ratio 710 if P is 2.7 cm distant from the centre O the length of AB is?
6.8 cm
How do you find the length of arc BC when the central angle of ab is 120 and the radius is 10?
This is your lucky day ! Watch now, as the Great and Powerful WA Contributorsolves your problem and answers your question without ever seeing the drawingthat's supposed to go along with it, and with no idea what 'BC' and 'ab' are . . .-- A whole circle has a central angle of 360 degrees.-- A whole circle with a radius of 10 has a circumference of [ (2 pi) x (radius) ] = 20 pi .-- A slice of cake with a central angle of 120 degrees is 1/3 of a circle.-- The arc at the fat end of the slice is 1/3 of the full circle's circumference = 20 pi/3 = 20.944 (rounded)-- Just in case 'BC' is the long arc, then its length is the other 2/3 of the whole circle= 2 x 20 pi/3 = 41.888 (rounded)Pay no attention to that old man behind the curtain.
If A (10 4) and B (2 19) what is the length of AB?
Length AB is 17 units
Two circles both of radii 4 have exactly one point in common If A is a point on one circle and B is a point on the other circle what is the maximum possible length for the line segment AB?
