Answer:

The volume of the observatory is 497.43 feet^{3}

Step-by-step explanation:

i) The diameter of the floor is 10 feet. The floor is circular and has a radius,          

    r =  \frac{10}{2} = 5 feet.

   Therefore the area of the circular floor of the observatory

     = \pi r^{2}      =   3.14159 × 5^{2}    =    78.54 feet^{2}

ii) The observatory is made up of two parts

  a)  3 foot tall cylinder

      ∴ volume of cylinder = \pi r^{2}   × h

                                         = 78.54 × 3

                                         = 235.62 feet^{3}

   b)  hemisphere = \frac{1}{2} × \frac{4}{3} \pi r^{3} = 0.6667 × 78.54 × 5   =  261.81 feet^{3}

    c) Therefore the total volume of the observatory is = a) + b)

         = 235.62 + 261.81 =   497.43 feet^{3}
