What is the name of a central angle?

A central angle is an angle whose vertex is at the center of a circle and whose sides (or rays) extend to the circumference, effectively subtending an arc on the circle. The measure of a central angle is equal to the measure of the arc it subtends. For example, if the central angle measures 60 degrees, the arc it subtends will also measure 60 degrees.


What is the measure of an arc that is intercepted by an inscribed angle of 30 degrees?

60 degrees


If arc EAB 195 degrees and arc EC 75 degrees what is the measure of angle EDC?

To find the measure of angle EDC, we can use the property that the angle formed by two tangents from a point outside a circle is half the difference of the measures of the intercepted arcs. Angle EDC intercepts arcs EAB and EC, so we calculate it as follows: Angle EDC = 1/2 (measure of arc EAB - measure of arc EC) = 1/2 (195° - 75°) = 1/2 (120°) = 60°. Thus, the measure of angle EDC is 60 degrees.


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°.


How many inches are there in one Minute Of Angle?

An arc-minute is 1/60 of a degree. It is not a measure of length, so you can't convert it to inches.


Find the arc length of a sector with a radius of 30 and an angle of 60 degrees?

arc length = angle/360 x r 60/360 x 30 = 5


In a circle of radius 60 inches a central angle of 35 will intersect the circle forming an arc of length?

To find the arc length of a circle given a central angle, you can use the formula: Arc Length = (θ/360) × (2πr), where θ is the central angle in degrees and r is the radius of the circle. For a circle with a radius of 60 inches and a central angle of 35 degrees, the arc length would be: Arc Length = (35/360) × (2π × 60) ≈ 36.7 inches.
