area x^2+2x+y^2+4y=20

Solution

area

x^{2} + 2 x + y^{2} + 4 y = 20

Solution

A = 25 π

Solution steps

A = π r^{2}

Find the radius

Radius given

x^{2} + 2 x + y^{2} + 4 y = 20 : r = 5

A = π 5^{2}

Refine

A = 25 π

Popular Examples

area x^2+y^2-6x+8y=144 area

x^{2} + y^{2} - 6 x + 8 y = 144

area 5x^2+5y^2-25=0 area

5 x^{2} + 5 y^{2} - 25 = 0

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

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

area x^2-6x+y^2-32y=0 area

x^{2} - 6 x + y^{2} - 32 y = 0

area 2x^2+2y^2-2x-2y-3=0 area

2 x^{2} + 2 y^{2} - 2 x - 2 y - 3 = 0
