an angle subtended by an arc is double at the center

true

Because it is still length. It is measured along a curve (arc), rather than a straight line. It can be found by multiplying the arc angle (in radians) by the radius. So a complete circle has an angle of 2*pi radians. Multiply this by the radius and you have 2*pi*radius, which is the circumference of a circle (measured in units, not square units).

The relation between the arc of length and the central angle is that the arc of length divided by one of the sides is the central angle in radians. If the arc is a full circle, then the central angle is 2pi radians or 360 degrees.

A sector is the area enclosed by two radii of a circle and their intercepted arc, and the angle that is formed by these radii, is called a central angle. A central angle is measured by its intercepted arc. It has the same number of degrees as the arc it intercepts. For example, a central angle which is a right angle intercepts a 90 degrees arc; a 30 degrees central angle intercepts a 30 degrees arc, and a central angle which is a straight angle intercepts a semicircle of 180 degrees. Whereas, an inscribed angle is an angle whose vertex is on the circle and whose sides are chords. An inscribed angle is also measured by its intercepted arc. But, it has one half of the number of degrees of the arc it intercepts. For example, an inscribed angle which is a right angle intercepts a 180 degrees arc. So, we can say that an angle inscribed in a semicircle is a right angle; a 30 degrees inscribed angle intercepts a 60 degrees arc. In the same or congruent circles, congruent inscribed angles have congruent intercepted arcs.

Each of the four pillars has a rectangular shape at ground level. There you could find a square angle (vertical side of the pillar + horizontal surface of the ground), and a square angle at each turn of every pillar. At the top of the arc you'll find another horizontal surface which is at a square angle with the vertical sides, plus four square angles at the turn of every side.

The area under the arc is the angular sweep of the arc (angle covered by the arc) divided by 360, multiply by pie times the square of the radius of the arc. If the value of pi is not given, 3.142 can be used as the value.

it is an arc of an angle that is adjacent

an angle subtended by an arc is double at the center

The angle or arc that when added to a given angle or arc equals a right angle in measureThat is, for any angle x less than 90Âº, the complement of xÂº = (90 - x)Âº. For example, the complement of 15Âº is (90 - 15 =) 75Âº.Here's a related answer for free: the supplement of an angle x is 180Âº - x.

it is more accurately called the "arc" the arc in circles are measure by the radius and the angle of projection. the formula is... s=r(angle) s is the arc length r is the radius length angle is the angle that the entire arc length makes
