Question 867660
A spherical bowl of radius 10 is filled with oil to such a depth that the oil surface is equal to 75(pi) square cm. Compute the volume of the oil and find the area covered by the oil in the tank.
---------------
The radius of the surface is sqrt(75) cm.
d = depth of oil
75 = d*(20-d) (products of chords)
d^2 - 20d + 75 = 0
d = 5, d = 15 cm
------
I'll find the area and volume later today.
