Question 1098378
1.water is poured into a plastic sphere of radius 15cm through a small hole on the top. it is noticed that the radius of surface of water is 12cm. find the depth of water in the sphere
--------------
The center of the sphere, S, the surface of the water and the sphere form a right triangle.
The distance from the center to the surface = sqrt(15^2 - 12^2) = 9 cm.
--------------
The depth of the water is either 15-9 = 6 cm
Or 15+9 = 24 cm.
