Answer:
(8,-2)
1256 feet^2
981.3 cm^2
Step-by-step explanation:
(x,y) --> (x+1, y-2)
(7,0) --> (7+1, 0-2) = (8,-2)
[tex]A=\pi r^2[/tex]
[tex]A = 3.14 (400)^2[/tex]
[tex]=1256 cm^{2}[/tex]
[tex]area_{sector}=\frac{angle}{360}*\pi r^2[/tex]
[tex]=\frac{45}{360} *(3.14)(50)^2[/tex]
[tex]=981.3 cm^2[/tex]
