Answer:

Step-by-step explanation:

Given that ,

Height of Buretts = 2.1 cm

                             = 0.021 m

A hemispherical knob on the one side of the cylinder of height = 80 cm

                                                                                                         = 0.8 m

To find the volume of attached structure.

So,

from the attached structure the volume  = ( volume of cylinder + volume of hemisphere )

                                              = ( \pi r^{2}h ~+~\frac{2}{3}\pi r^{3} )

                                             

                                             = \pi r^{2}(\frac{2}{3}r~+ ~h)

     

                                            = \pi r^{3}(\frac{2}{3}*0.8 ~+~0.021)

     

                                           = \pi r^{2}(0.53333333333~+~0.021)

                                          = \pi r^{2} *( 0.5543333333)

                                         

                                         = (3.14* 0.8*0.8) ( 0.5543333333)

           

                                        = 1.11398826667 m^{3}

Therefore total volume = 1.11398826667 m³
