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.

To find the area of the shaded sector, first determine the area of the entire circle using the formula (A = \pi r^2), where (r) is the radius of the circle. Next, find the fraction of the circle represented by the sector by dividing the central angle of the sector (in degrees) by 360 degrees or using the angle in radians divided by (2\pi). Multiply the area of the circle by this fraction to get the area of the shaded sector.
It is found by: (sector area/entire circle area) times 360 in degrees

Area of sector/Area of circle = Angle of sector/360o Area of sector = (Area of circle*Angle of sector)/360o
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
Multiply ( pi R2 ) by [ (angle included in the sector) / 360 ].
It depends on what information you have: the radius and the area of the sector or the length of the arc.
