The area is r^2*x where r is the radius of the circle and x is the angle measured in radians.

If you are still working in degrees then Area = (y/180)*r^2, where the angle is y.

Find the area of the shaded sector when the radius is 12 and the not shaded is 100?

To find the area of the shaded sector, we first need to determine the area of the entire circle with a radius of 12, which is calculated using the formula (A = \pi r^2). Thus, the area of the entire circle is (A = \pi (12^2) = 144\pi). If the not shaded area is 100, the area of the shaded sector is then (144\pi - 100). Therefore, the area of the shaded sector is approximately (144\pi - 100) square units.

Find the area of the shaded sector round to the hundredth shaded sector is 155 the rest is 4.3?

To find the area of the shaded sector, we need to determine the total area represented by the shaded and non-shaded parts. If the shaded sector is 155 and the rest is 4.3, the total area is 155 + 4.3 = 159.3. The area of the shaded sector is already given as 155, so rounding it to the hundredth gives us 155.00.
