The volume of the solid formula is

From the diagram base of the solid is composed with a rectangle and a half circle.

So, use the sum of the areas of the rectangle and half circle to find B.

Area of a rectangle is  and area of half circle is .

   (Substitute 9 for l , 7 for w , 3.14 for and 4.5 for r)

                         (Multiply: )

                                  (Add: )
