Find the equation of a sphere if one of its diameters has endpoints: (-14. -3, -6) and (-4, 7, 4) Note that you must move everything to the left hand side of the equation and that we desire the coefficients of the quadratic terms to be 1.

Answer:


x^2+y^2+z^2-18x-4y+2z-21=0

Explanation:

From the question we are told that:

Diameters has endpoints:
(-14. -3, -6) & (-4, 7, 4)

Generally the equation for Center of The sphere is mathematically given by


C=((-14+(-4))/(2),(-3+(7))/(2),(-6+(4))/(2))


C=(9,2,-1)

Generally the equation for Radius of the sphere is mathematically given by


R=√((9-2)^2+(2-9)^2+(-1-2)^2)


R=√(107)

Therefore the Equation of the Sphere is


(x-9)^2+(y-2)^2+(z+1)^2=107


(x^2-18x+81)+(y^2-4y+4+(z^2+2z+1))=107


x^2+y^2+z^2-18x-4y+2z-21=0
