Expert Answer
From the figure, triangle ADE is similar to triangle ACB
Hence, AD/ AC = DE/CB
AC = slant height = 10 cm
AD = AC-CD = 10-6=4 cm
Hence, 4 / 10 = r / 6 (r is radius of sphere)
r = 12/5 cm
fraction of water flown out = Volume of immersed sphere / volume of cone = (4/3)
r3 / (1/3) R2h
r = 12/5 cm, R= 6cm, h = 8cm
Hence the fraction can be found out.
