Question

Water fills a spherical tank of diameter 16 meters until the water is 4 meters deep at the lowest point in the tank. What is the diameter of the surface of the water?

Answer 1

Answer:

8$\sqrt{3}$  meters

Step-by-step explanation:

Since all cross-sections of a sphere are circles.

so,  $r^{2}$ = 4*(16 - 4)  =48

where, r= radius of the circular water surface

r =$\sqrt{48}$ = 4$\sqrt{3}$ meters .

Hence,

diameter= 2r = 2* (  4$\sqrt{3}$)

diameter = 8$\sqrt{3}$  meters.
