Because you will be using the number pi to find the area of the circle, some rounding will be required.
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.
That would certainly do it.

It is found by: (sector area/entire circle area) times 360 in degrees
area of sector-area of triangle
Area of sector/Area of circle = Angle of sector/360o Area of sector = (Area of circle*Angle of sector)/360o
35.35 sq un
area of sector = (angle at centre*area of circle)/360
find the area of the shaded sector 12cm and 24°
That would certainly do it.

A hard QUESTION
It depends on what information you have: the radius and the area of the sector or the length of the arc.
Multiply ( pi R2 ) by [ (angle included in the sector) / 360 ].
For a circle where sector measures 10 degrees and the diameter of the circle is 12: Sector area = 3.142 square units.
