area x^2+y^2-2x+4y-31=0

Solution

area

x^{2} + y^{2} - 2 x + 4 y - 31 = 0

Solution

A = 36 π

Solution steps

A = π r^{2}

Find the radius

Radius given

x^{2} + y^{2} - 2 x + 4 y - 31 = 0 : r = 6

A = π 6^{2}

Refine

A = 36 π

area 4x^2+4y^2-4x+2y-1=0 area

4 x^{2} + 4 y^{2} - 4 x + 2 y - 1 = 0

area x^2+y^2=4 area

x^{2} + y^{2} = 4

area (x+4)^2+(y-6)^2=18 area

(x + 4)^{2} + (y - 6)^{2} = 18

area+x^2+y^2=4 area

+ x^{2} + y^{2} = 4

area 4x^2+4y^2=64 area

4 x^{2} + 4 y^{2} = 64
