.the same but you just round the numbers first
Because you will be using the number pi to find the area of the circle, some rounding will be required.
You would have to round since area will not be able to be represented without rounding.

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.

To find the nearest square unit of a given area, first calculate the square root of the area to determine the side length of the square. Round this side length to the nearest whole number, then square that rounded value to find the nearest square unit. For example, if the area is 20, the square root is approximately 4.47, rounding to 4 gives a nearest square unit of 16 (4²).
To find the rounding of 428731 and 175842 together, first, you add the two numbers: 428731 + 175842 = 604573. Rounding 604573 to the nearest thousand gives you 605000. Therefore, the rounded sum of 428731 and 175842 is 605000.
