diameter x^2+y^2=81

Solution

diameter

x^{2} + y^{2} = 81

Solution

d = 18

Solution steps

d = 2 r

Find the radius

Radius given

x^{2} + y^{2} = 81 : r = 9

d = 2 \cdot 9

Refine

d = 18

Popular Examples

diameter x^2+y^2-2x+6y-15=0 diameter

x^{2} + y^{2} - 2 x + 6 y - 15 = 0

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

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

diameter 3x^2+3y^2+2x-4y-1=0 diameter

3 x^{2} + 3 y^{2} + 2 x - 4 y - 1 = 0

diameter x^2+y^2-16=0 diameter

x^{2} + y^{2} - 16 = 0

diameter (x-1)^2+y^2=1 diameter

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