What else can I help you with?
A central angle of a circle of radius 8 cm intercepts an arc of 12.5 cm express the central angle in degrees?
89.52 degrees.
Convert degrees into a percent?
To obtain the percent value for an angle (in slopes and inclines), calculate the tangent of that angle in degrees, then multiply the figure by 100.
If a central angle measures 180 degrees what is it called?
An angle of between 90 degrees and 180 degrees is called an obtuse angle, an angle that is exactly 180 degrees is called a straight angle (because it creates a straight line), and an angle of more then 180 degrees is called a reflex angle.
What is the angle for 43.75 percent of a circle?
157.5 degrees
What is the angle for 40 percent of a circle?
144 degrees
What is the central angle of a 42 percent section of a circle graph?
151.2 degrees (42/100)*360 degrees
How do you find the central angle of a circle?
Put the percent in decimal form, than mutiply it by 360 degrees.
Does a central anglehave to equal 90 degrees?
a central angle does NOT have to equal 90 degrees
What is the measure in degrees of each central angle of a regular 15-sided polygon?
The central angle of a n-sided regular polygon = 360 degrees / n. Hence, the central angle of a 15-sided regular polygon = 360 degrees / 15 = 24 degrees ============================

89.52 degrees.

What is 45 percent as an angle on a circle graph?
It is an angle of 162 degrees.
What is 33 percent as an angle?
118.8 degrees.
How do you find the central angle in a circe?
The central angle of the circle is the angle around a point and so, be definition, it must be 360 degrees.
How many degrees in the central angle of a circle whose secion percent is 75 percent?
There are, of course, 360 degrees all the way around a circle. So 75% = 75/100, and (75/100)*360° = 270°
What is the relation between the arc length and angle for a sector of a circle?
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.
If a central angle measures 180 degrees what is it called?
An angle of between 90 degrees and 180 degrees is called an obtuse angle, an angle that is exactly 180 degrees is called a straight angle (because it creates a straight line), and an angle of more then 180 degrees is called a reflex angle.
