area x^2-2x+y^2+2y=7

Solution

area

x^{2} - 2 x + y^{2} + 2 y = 7

Solution

A = 9 π

Solution steps

A = π r^{2}

Find the radius

Radius given

x^{2} - 2 x + y^{2} + 2 y = 7 : r = 3

A = π 3^{2}

Refine

A = 9 π

Popular Examples

area (x+2)^2+(y-4)^2=25 area

(x + 2)^{2} + (y - 4)^{2} = 25

area (x+1)^2+(y-1)^2=40 area

(x + 1)^{2} + (y - 1)^{2} = 40

c i rc l e, f in d A re a, g i v e n r = c : (2, - 1) r = 3

area x^2+y^2-12y+32=0 area

x^{2} + y^{2} - 12 y + 32 = 0

area x^2+y^2=20 area

x^{2} + y^{2} = 20
