From Gyanesh Anand
Cut it into different sectors of small central angle.then find the area of each sector and add them up to find that area of circle is equal to 2*pi*r

What is an angle in a circle whose vertex is at the center of the circle?
Central Angle
An angle whose vertex is the center of the circle?
That is the central angle.
What is an angle whose vertex is at the center of a circle?
A central angle.The section of the circle formed by that angle and the part of the circle (the part being the circumference) between the radii is called a sector.
If the radius of a circle is doubled how is the length of the arc intercepted by a fixed central angle changed?
If the radius of a circle is tripled, how is the length of the arc intercepted by a fixed central angle changed?
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) .
What is a central angle?
Central Angle An angle in a circle with vertex at the circle's center.
What is an angle in a circle whose vertex is at the center of the circle?
Central Angle
What are the central angles of a circle?
The central angle is the angle that has its vertex at the center of the circle.
Is a central angle of a circle is an angle whose vertex is anywhere inside the circle?
No. It's a central angle only if its vertex is at the center of the circle.
What is an arc central angle and radius of the circle?
Radius: A line from the center of a circle to a point on the circle. Central Angle: The angle subtended at the center of a circle by two given points on the circle.
What is the central angle of the circle?
An angle with its vertex on the center point of the circle.
What is a central angle in a circle?
An angle that's vertex is on the center of the circle.
What is an angle formed by two radii of a circle called?
central angle central angle
If a circle is divided into 5 sections by 5 radii and each of the central angles formed are of equal measure what is the measure of each central angle?
72 degrees 72 degrees
