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)

$A=\pi r^2$

$A = 3.14 (400)^2$

$=1256 cm^{2}$

$area_{sector}=\frac{angle}{360}*\pi r^2$

$=\frac{45}{360} *(3.14)(50)^2$

$=981.3 cm^2$

Write the standard equation of the circle with the given center that passes through the given point

Kitty [74]

Circle equation
(x - h)^2 + (y - k)^2 = r^2
Since radius isn't given use the center and point, with the distance formula, to find the radius.
D=sqrt((x2-x2)^2+)y2-y1)^2)
D=sqrt((1-0)^2+(2-6)^2
D=sqrt(1+16)
D=sqrt 17
radius = sqrt 17
(h, k) is the center and r is the radius
(x - 1)^2 + (y - 2)^2 = 17
