How do you work out the area of a sector using the angle and radius?
the area of a sector = (angle)/360 x PI x radius x radius pi r squared
What is the area of the sector a circle with a radius of 2 inches and an arc of 60 degrees?
The area of the sector of a circle with a radius of 2 inches and an arc of 60 degrees: 2.094 square inches.
In a circle a 90 degrees sector has area 16pi ft2. what is the radius of the circle?
The radius is 8 feet.
What is the radius of circle with an area sector of 662.89?
The area of a circle is derived from Pi x r2 where Pi = 3.14 and r = the radius, therefore a circle with an area of 662.89 has a radius of 14.5
What is the arc measure of a sector with area 38.485 ft2 and radius 7?
Area of sector: 38.485 sq ft Area of circle: 153.93804 sq ft Arc in degrees: (38.485/153.93804)*360 = 90.00114592 or about 90 degrees Arc in feet: 10.99557429 or about 11 feet
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
What is the area of a sector with radius 6 and measure of arc equal to 120 degrees?
Its square area is: 1/3*pi*62 = 12*pi or 37.699 to 3 decimal places
How do you find radius using angle of a sector?
It depends on what else is known about the sector: length of arc, area or some other measure.
Area of a sector?
pi times the radius squared times the measure of the arc divided by 360
What is the area of a sector with radius 10 and measure of the arc equal to 45 degrees?
Area of circle sector: 45/360 times pi times 10 squared = 39.27 square units rounded to two decimal places
Find the area of a sector of a circle with a 2 feet radius formed by a 30 degree angle?
the formula for the area of a sector is measure of arc/360 times (pi)(radius squared) it should come out to be about 1.046 or 1.047, or 1/3(pi) the formula for the area of a sector is measure of arc/360 times (pi)(radius squared) it should come out to be about 1.046 or 1.047, or 1/3(pi)
If a circle has a radius of 12 cm and a sector defined by a 120 degree arc what is the area of the sector?
if a circle has a radius of 12cm and a sector defined by a 120 degree arc what is the area of the sector
What is the area of a sector whose central angle is ninety degrees and has a radius of ten inches?
Well a circle has 360 degrees so a sector of 90 degrees has an area equal to 90/360 (or 1/4) of a circle with the equivalent radius. The area of a circle is defined as PI*Radius^2 so the area of a 90 degree sector will be 1/4*PI*Radius^2. The area will be 1/4*3.14*10^2 or 78.5 in^2.
What is the measure of the central angle with a sector area of 169.56 and a radius of 9?
Radius is 9 so area of complete circle (360o) is 81 x 3.14 ie 254.34. Angle of sector is therefore 360 x 169.56/254.34 which is 240o
How do you work out the area of a sector using the angle and radius?
the area of a sector = (angle)/360 x PI x radius x radius pi r squared
If the ratio of a circle's sector to its total area is 78 what is the measure of its sector's arc?
Length of arc = angle of arc (in radians) × radius of circle With a ratio of 7:8 the area of the sector is 7/8 the area of the whole circle. This is the same as saying that the circle has been divided up into 8 equal sectors and 7 have been shaded in. Dividing the circle up into 8 equal sectors will give each sector an angle of arc of 2π × 1/8 7 of these sectors will thus encompass an angle of arc of 2π × 1/8 × 7 = 2π × 7/8 = 7π/4 Thus the length of the arc of the sector is 7π/4 × radius of the circle. --------------------------------- Alternatively, it can be considered that as 7/8 of the area is in the sector, the length of the arc is 7/8 the circumference of the circle = 7/8 × 2π × radius = 7π/4 × radius.
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?
