area x^2+y^2=4

Solution

area

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

Solution

A = 4 π

Solution steps

A = π r^{2}

Find the radius

Radius given

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

A = π 2^{2}

Refine

A = 4 π

Popular Examples

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

area x^2+y^2-6x+4y+4=0 area

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

area x^2+y^2<=+16 area

x^{2} + y^{2} \leq + 16
