- The area of the circle is:

A=πr²

A is the area of the circle.
π=3.14
r is the radius of the circle.

- To calculate the area of <span> the sector indicated in the problem, you must apply the following formula:

As=(</span>θ/2π)πr²

As is the area of the sector.
θ is the central angle (θ=2π/9)
π=3.14
r is the radius.

- First, you must find the radius:

r=Diameter/2
r=20.6 mm/2
r=10.3 mm

- Now, you can substitute the values into the formula As=(θ/2π)πr². Then, you have:

As=(θ/2π)πr²
As=(2π/9/2π)(π)(10.3)²
As=(π/9π)(π)(10.3)²
As=(3.14/9x3.14)(3.14)(10.3)²

- Finally, the area of the sector is:

As= 37.01 mm²

Just answers since long and many simplifiction
it's like doing those multiplication memory things that had like 100 questions but now with algebra fractions

5. fourth or $\frac{5x-15}{x^{2}-3x-28}$
6. third or $\frac{4x+25}{x^{2}+5x+4}$
7.the answe ris x+3 since it can be factored out of the 5x+15 tingie (second )
8. fourth or $\frac{x^{2}+4x}{4}$
9. fourth or $\frac{2y+6}{9y-7}$ times $\frac{3}{2}$
10. third or $\frac{(x+3)(x+8)}{(x-8)(x-8)}$
11. second or $\frac{x-5}{x-4}$
12. third or 11(x+7)=60
