What is the radius of a circle if it has a sector area of 662.89 and a 190 degree measure?
For A+ it's 20
Is the area of a sector the area of the circle multiplied by the fraction of the circle covered by that sector?
true
What is the area of a circle if the area of its sector is 49?
The area of the circle is(17,640)/(the number of degrees in the central angle of the sector)
What is area to the nearest tenth of a 120 degree sector of a circle with radius of 8 ft?
Area of whole circle = pi*r2 = 64*pi Area of Sector = Area of Whole Circle * Angle of Sector/Angle of Whole Circle = Area of Whole Circle * 120/360 = Area of Whole Circle / 3 = 64*pi/3 = 67.0 to the nearest tenth.
What is the approximate area of a sector with radius equal to 8 and measure of arc equal to 300 degrees?
The area of the full circle is (pi) R2 = 64 pi.We call a full circle "360 degrees".The 300-degree sector is (300/360) = 5/6 of the full circle, so its area is(5/6) x (64 pi) = 167.55 square units (rounded)
True or fulse To find the area of a sector you multiply the area of the circle by the measure of the arc determined by the sector?
fulse
To find the area of a sector you multiply the area of the circle by the measure of the arc determined by the sector?
Area of sector/Area of circle = Angle of sector/360o Area of sector = (Area of circle*Angle of sector)/360o
To find the area of a sector you multiply the area of the circle by the fraction of the circle covered by that sector?
That would certainly do it.
A circle has an area of 30 in What is the area of a 60 sector of this circle?
Divide the area of the sector by 360 and multiply it to the area. The area of the sector is 5 square inches.
How can you find the angle of a sector in a circle?
Multiply ( pi R2 ) by [ (angle included in the sector) / 360 ].
How do you find an area of a sector of a circle?
Multiply ( pi R2 ) by [ (angle included in the sector) / 360 ].
When a piece of a circle is determined by two radii what is that piece called?
Sector
If the arc length of a sector in the unit circle is 3 radians what is the measure of the angle of the sector?
In a unit circle, the arc length ( s ) is directly equal to the angle ( \theta ) in radians. Therefore, if the arc length of a sector is 3 radians, the measure of the angle of the sector is also 3 radians.
A circle has an area of 24 m What is the area of a 45 sector of this circle?
Divide the angle sector by 360 and multiply it by 24 square meters. The area is equal to 3 square meters.
A circle has a radius of 6.5 inches. The area of a sector of this circle is 75 in2. Approximate the measure of the central angle, in radians, of this sector, rounded to the nearest tenth?
6.5
When was the latitude of the Arctic Circle determined?
The latitude of the Arctic Circle was determined around 300 B.C. by the Greek astronomer and mathematician Eratosthenes. He calculated it to be approximately 66.5 degrees north of the Equator.
What is the radius of a circle if it has a sector area of 662.89 and a 190 degree measure?
For A+ it's 20
