Answer to: The area of a sector of a circle with a central angle of 6 pi/11 rad is 23 m^2. Find the radius of the circle. (Round the answer to one...
The area of a sector is a fraction of the area of the circle. This area is proportional to the central angle. In other words, the bigger the central angle, the larger is the area of the sector. The following diagrams give the formulas for the area of circle and the area of sector....
The area of a circle is pi r^2, yes? So if you have, say, 30 degrees of central angle, the area will be 30/360 of the area of the total circle. In that case, you'd take (30/360) * pi * r^2. The sector is just a fraction of the circle, so use a fractio...
Area of a Sector calculation Example: find the area of a sector Area of a sector formula The formula for the area of a sector is (angle / 360) x π x radius2. The figure below illustrates the measurement: As you can easily see, it is quite similar to that of a circle, but modifi...
