Answer 1

Answer:

h=126/122=1.032m

Step-by-step explanation:

volume of the well =volume of the circular ring

r1=3/2[radius of well]

h=14

volume of the well=pi×r1²×h=22/7×[3/2]²×14

= 99m²

volume of circular ring=volume of the well

volume of circular ring = volume of whole cylinder -volume of cylinder from the well= π[r2]²h-π[r1]²h

=π×[3/2+4]²×h-π×[3/2]²×h

=πh[121/4-9/4]=πh[122/4]

126π/4=πh[122/4]

h=126/122=1.032m
