Answer:
44.68 square cm
Step-by-step explanation:
To find the area of the whole circle you use the formula pie x r^2
then multiply that area by 40/360 because that is the area of the sector

Step-by-step explanation:
Answer:
We know that, a³ - b³ = (a - b)(a² + ab + b²)
Now,
- x³ - 27
- (x)³ - (3)³
- (x - 3)(x² + 3x + 9)
Therefore,
- <u>(x² + 3x + 9)</u> is the other factor.
To find the surface area of ANY prism you need to find the area of individual shape first.
To find 2 faces of the prism, you will need to do bxh. As there is 2 of the same rectangle , you need to multiply it by 2. Therefore, the first number you need is 16m squared.
To find the next part of the prism, you will need to do 2m x 3m which is 6m. You need the area so 6m squared (The units are important). There are also 2 of these, so multiply it by 2 to get 12m squared.
For the final part of the prism, you will need to do 4m x 3m which is 12m squared. There are 2 of these so the it is 24m squared.
Finally, you will need to add all these figures up.
<u>16m squared + 12m squared + 24m squared = 52m squared</u>
I'm not 100% sure what you're asking, but i think it wants:
50,000 + 25,000 = 75,000 - so B is the answer
to do it you basically just round the number to the nearest 1000 and add
