A solid consistin

Radius (r) of hemispherical part = Radius (r) of conical part = 60 cm

Height (h) of conical part of solid = 120 cm

Height (H) of cylinder = 180 cm

Radius (r) of cylinder = 60 cm

Volume of water left = Volume of cylinder - Volume of solid

= Volume of cylinder – (Volume of cone + Volume of hemisphere)

= πr²H– (r²h + r³)

= [π (60)² (180) ]– [ (60)² × 120 +  (60)³]
= 648000 π - ( 144000 π + 144000 π )
= 648000 π  - 288000 π 
= 360000π

= 1131428.57 cm³
= 1.131 m³(approx)
