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).
324.47 square feet
The area of a circle whose radius is 19 centimeters is: 1,134 cm2
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.
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 ].

if a circle has a radius of 12cm and a sector defined by a 120 degree arc what is the area of the sector
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.
The area of the sector of the circle formed by the central angle is: 37.7 square units.
Radius is x2 so area is x4.
The area of a circle whose radius is 19 centimeters is: 1,134 cm2
3850m is the area of the a circle whose radius of 7meaters
If the sector of a circle has a central angle of 50 and an area of 605 cm2, the radius is: 37.24 cm
The radius of a circle whose area is 3.14 square centimeters is: 1 cm
0. There is no circle so no shaded area of a circle!
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.
