The area of a circle of radius 12 is 144 pi; the part of the circle defined by such an arc (the arc itself, of course, has an area of 0) is 100/360 of that, which simplifies to 40 pi. To 3 significant digits, that is 126.
89.52 degrees.
It is certainly possible. All you need is a the second circle to have a radius which is less than 20% of the radius of the first.
the radius
360 degrees
An eighth of the area of the circle which, since neither its radius, diameter nor circumference are known, is an unknown quantity.
89.52 degrees.
The area of the sector of the circle formed by the central angle is: 37.7 square units.
It is certainly possible. All you need is a the second circle to have a radius which is less than 20% of the radius of the first.
Radius: A line from the center of a circle to a point on the circle. Central Angle: The angle subtended at the center of a circle by two given points on the circle.

the radius
-- Circumference of the circle = (pi) x (radius) -- length of the intercepted arc/circumference = degree measure of the central angle/360 degrees

Find the area of the shaded sector. radius of 3 ...A+ = 7.07
If this is a central angle, the 72/360 x (2xpix4) = 5.024
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 measure of the central angle divided by 360 degrees equals the arc length divided by circumference. So 36 degrees divided by 360 degrees equals 2pi cm/ 2pi*radius. 1/10=1/radius. Radius=10 cm.
