Question

Find the equation of the sphere with centre(1,1,1)and radius 5.​

Answer 1

We have,

Centre =(3,2,1)

Radius =5

We know that

(x−h)

2

+(y−k)

2

+(z−l)

2

=r

2

Therefore, the equation of given sphere

(x−3)

2

+(y−2)

2

+(z−1)

2

=5

2

(x−3)

2

+(y−2)

2

+(z−1)

2

=25

x

2

+y
