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 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 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 radius of the sector when the angle is 21 and the arc length is 25?
Circumference of circle: 360/21 times 25 = 3000/7 Radius of sector: (3000/7) divided by (2*pi) = 68 units to the nearest integer
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)

What is the radius of a circle if it had a 90 degree sector and an area if 64pi?
From your question, we can't tell whether [ 64 pi ] is the area of the circleor the sector.The area of a circle is [ pi R2 ].If [ 64 pi ] is the area of the circle, then the radius is [ 8 ], and we don't careabout the sector.If [ 64 pi ] is the area of the sector, then the area of the full circle is [ 256 pi ](because the 90-degree sector is 1/4 of the circle), and the radius is [ 16 ].

What is the radius of a circle with a sector are of 662.89?
Not enough information is given to work out the radius of the circle as for instance what is the length of sector's arc in degrees
What is the area of a 30 degree sector of a circle with a radius of 36?
Area of the circle = pi*362 = 1296*pi Area of the sector = 30/360 of 1296*pi = 108*pi square units
Find the area of a 120 degree sector of a circle with a radius of 6?
There are 360 degrees in a circle so it will be 1/3 of pi*62 square units
The area of the sector formed by the 110 degree is 50 units what is the radius of the circle?
If you mean a sector with an arc of 110 degrees and an area of 50 square units Area of all the circle: 360/110 times 50 = 163.'63' square units Radius of the circle is the square root of 163.'63'/pi = 7.2171377402 So the radius of the circle is about 7 units
