Area of the circle = pi*362 = 1296*pi
Area of the sector = 30/360 of 1296*pi = 108*pi square units
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 ].
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
The radius is 8 feet.
The area of the sector of a circle with a radius of 2 inches and an arc of 60 degrees: 2.094 square inches.
A 72 degree sector represents 72/360 = 1/5 of a circle. Area of whole circle = pi*r2 = 100*pi So area of 1/5 circle = 20*pi = 62.83 cm2 (approx).
if a circle has a radius of 12cm and a sector defined by a 120 degree arc what is the area of the sector
The area of a sector in a circle if the radius is 4 cm and the arc has degree 120 is: 16.76 cm2
The radius is 12

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.
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.
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
If the sector of a circle has a central angle of 50 and an area of 605 cm2, the radius is: 37.24 cm
0. There is no circle so no shaded area of a circle!
