How to find a sector area in a circle if you have only the arc length?
If you have the arc length:where:L is the arc length.R is the radius of the circle of which the sector is part.
How do you find the area of a sector of a circle when you're given only the radius and not the degrees?
You cannot. The angle of the sector MUST be given, although that might be implicitly rather than explicitly.
Finding the length of sector AB your central angle is 75 and the radius of the circle is 36 For some reason 23.6 is the only answer that comes up.?
A sector of a circle is a part of a circle formed by two radii and the arc they intercept; it is a fractional part of a circle. So that the question should be, "find the area A of the sector OAB ...".There are 360⁰ in a circle. So the area of the 75⁰ sector is 75⁰/360⁰, or 5/24, the area of the circle.A = (5/24)(pi )(362) ≈ 848.23 square units.
Where can i find blossomin fusionfall?
At Sector V on top of the treehouse only in the Past .
Why is sine used?
when trying to find the angle of a right triangle using only the opposite leg and the hypotenuse, eg. angle =sin opp leg over hyp * * * * * Also to find the area of a triangle if two sides and the included angle are known. Or the area of a sector of a circle.
What is the area of a sector of a circle with central angle 140 degrees and radiusn6 inches?
The area of the whole circle would have been π*62 But instead of 360 degrees for the whole circle, the sector measures only 140 degrees. That is to say, the sector is 140/360 of the whole circle. Area = π*62*140/360 = 43.9823 sq inches.
How can you find the direction of motion from a distance x axis and time y axis graph?
You can't. Such a graph is only appropriate for motion in a single dimension.
How do you work out the area of a sector when given the length of the arc?
If you're only given the length of the arc, then you can't. You also need to know the fraction of the circle that's in the sector. You can figure that out if you know the angle of the arc, or the radius or diameter of the circle. -- Diameter of the circle = 2 x (radius of the circle) -- Circumference of the circle = (pi) x (Diameter of the circle) -- (length of the arc)/(circumference of the circle) = the fraction of the whole circle that's in the sector or -- (degrees in the arc)/360 = the fraction of the whole circle that's in the sector -- Area of the circle = (pi) x (radius of the circle)2 -- Area of the sector = (Area of the circle) x (fraction of the whole circle that's in the sector)
How do you find the area of only .25 a circle?
Find the area of the circle and divide by 4.
What is the shaded sector of the if radius is 3 and the degrees is 90?
It depends whether the UNSHOWN figure has the shaded sector as the sector which includes the 90° angle, or the one which excludes it. Assuming that it is the sector including the 90° angle, ie the question should have been written: What is the area of a sector of a circle with a radius of 3 units when the angle of the sector is 90°? It is a fraction of the whole area of the circle. The fraction is 90°/360° (as there are 360° in a full turn and only 90° are required) = 1/4 Area circle = π × radius² = π × (3 units)² = 9π square units → area 90° sector = ¼ × area circle = ¼ × 9π square units = 9π/4 square units ≈ 7.1 square units
Find area of shaded sector?
theta (angle) _____ X pi r squared 360 Note that if the angle is measured in radians, then you only need to do Θ*r². A full circle is 360° or 2*pi radians
What is the tertiary sector?
In tertiary sector no production is done only the services are provided such as transport , banking , communication etc. And this sector is also called service sector.
