Question

How do you find an equation of the sphere with center (1, −7, 4) and radius 5?

Answer 1

We know that equation of a

sphere whose center is (a,b,c)

having radius r is given by

(x-a)^2+(y-b)^2+(z-c)^2=r^2

Therefore, equation of the

required sphere is given by

(x-1)^2+(y+7)^2+(z-4)^2=5^2.

I hope you will get it.
