The sector must contain an isosceles triangle and so:-
Area of sector: 40/360*pi*3*3 = pi
Area of triangle: 0.5*3*3*Sin(40 degrees) = 2.892544244
Area of segment: pi-2.892544244 = 0.249 square cm rounded to 3 decimal places

What are segments of a circle called?
Exactly as in the question and a segment of a circle is the area enclosed by a chord and an arc of a circle.
What does segment means on geometry?
The area within a circle enclosed by a chord and an arc
What is the area of a circle's segment that has a chord length of 30 cm and a diameter of 36 cm showing work?
1. The segment will be enclosed within a sector of radii 18 cm and an arc angle of about 113 degrees. 2. Area of sector: 113/360*pi*18*18 = 319 square cm rounded. 3. Area of segment: 316-area of isosceles triangle contained in the sector = 170 square cm rounded.
Is a circle an arc?
an arc is a segment of a circle. If the arc subtends a full angle of 360 degrees, then the arc is a circle; but this is a special case of an arc.
What is the radius and diameter of a circle?
The radius of a circle is a line segment joining any point of the boundary of the circle to its centre. A diameter is a line segment from a point of the boundary of the circle which passes through the centre and ends at the boundary on the opposite side.
What is a segment has endpoints?
A segment is the area within a circle enclosed by an arc and a chord
What are segments of a circle called?
Exactly as in the question and a segment of a circle is the area enclosed by a chord and an arc of a circle.
The part of a circle enclosed by to radii and an arc?
Is a SECTOR. or SEGMENT.
What does segment means on geometry?
The area within a circle enclosed by a chord and an arc
What is the area enclosed by a chord of a circle?
The area enclosed by a chord is equal to the area enclosed by a segment minus the area enclosed by the triangle with the same corners as the segment. To visualise it, draw a circle and put a chord on it. Label the chord AB and the centre of the circle C. The area of sector AB equal to the area of sector ABC minus the area of triangle ABC.
What is the relationship between segments and circles?
A segment of a circle is an area enclosed by a chord and an arc.
What is the area of a circle's segment that has a chord length of 30 cm and a diameter of 36 cm showing work?
1. The segment will be enclosed within a sector of radii 18 cm and an arc angle of about 113 degrees. 2. Area of sector: 113/360*pi*18*18 = 319 square cm rounded. 3. Area of segment: 316-area of isosceles triangle contained in the sector = 170 square cm rounded.
What is 20 percent on a circle graph?
A segment that covers 1/5 of the circle. ie 72 degrees
What are its parts of circle?
Circumference is the perimeter of a circle Diameter is the length spanning a circle cutting through its center Radius is half the length of a circle's diameter Tangent is a straight line that touches a circle's circumference at one point Arc is part of a circle's circumference Chord is a straight line joining any two points of a circle's circumference Sector is the area enclosed by an arc and two radii Segment is the area enclosed by arc and a chord Circle's circumference divided by its diameter is equal to the value of pi Area of a circle = pi*radius squared There are 360 degrees around a circle
Is a circle an arc?
an arc is a segment of a circle. If the arc subtends a full angle of 360 degrees, then the arc is a circle; but this is a special case of an arc.
What is a segment in a circle?
A segment of a circle is known as an arc.A segment of a circle is called a arc.A segment of a circle is known as an arc.
What is a part of a circle between two points on the circle?
The line connecting the points is called a chord; the part of the perimeter of the circle enclosed is called an arc; the area between an arc and the chord is called a circular segment.
