Explanation:
From the question we are told that:
Diameters has endpoints:
![(-14. -3, -6) & (-4, 7, 4)](https://img.qammunity.org/2022/formulas/mathematics/college/arkfuzl57hcx45wr4nuoan7kuu8sbhmb8p.png)
Generally the equation for Center of The sphere is mathematically given by
![C=((-14+(-4))/(2),(-3+(7))/(2),(-6+(4))/(2))](https://img.qammunity.org/2022/formulas/mathematics/college/gebzpg00m563evt7htn3e8opqxd0heij2t.png)
![C=(9,2,-1)](https://img.qammunity.org/2022/formulas/mathematics/college/vjtjzf0ikle2toht21m86ait96rvk64fuy.png)
Generally the equation for Radius of the sphere is mathematically given by
![R=√((9-2)^2+(2-9)^2+(-1-2)^2)](https://img.qammunity.org/2022/formulas/mathematics/college/nppsbgiidhd772e8vw70x5h61ny5wldy8q.png)
![R=√(107)](https://img.qammunity.org/2022/formulas/mathematics/college/g8yfmji6sdbbmwjxcdcj7blccqa0inonww.png)
Therefore the Equation of the Sphere is
![(x-9)^2+(y-2)^2+(z+1)^2=107](https://img.qammunity.org/2022/formulas/mathematics/college/9wtguwmla6gp90vn5wqjmhjzkx9qlva8fi.png)
![(x^2-18x+81)+(y^2-4y+4+(z^2+2z+1))=107](https://img.qammunity.org/2022/formulas/mathematics/college/gw4egyvliqu7n0p4ys1cjllqc0p3kokxbj.png)
![x^2+y^2+z^2-18x-4y+2z-21=0](https://img.qammunity.org/2022/formulas/mathematics/college/gchj4n5s3ezlbnlu8fmuunuh3badlutpap.png)
