Given:

Diameter=40 feet

so radius=20 feet(d=2r)

Height of 2nd tank= 130 feet

Required:

Volume of sphere

Volume of cylinder

Explanation:

First of all we are going to calculate volume of sphere=

[tex]\begin{gathered} \frac{4}{3}\pi r^3 \\ =\frac{4}{3}\times3.14\times20\times20\times20 \\ =33,493.33feet^3 \end{gathered}[/tex]

Then we are going to calculate volume of cylinder=

[tex]\begin{gathered} =\pi r^2h \\ =3.14\times20\times20\times130 \\ 163,280feet^3 \end{gathered}[/tex]

and the vertically cross- section of tank 2 is a rectangle.

Required answer:

volume of sphere is 33,493.33

volume of cylinder=163,280

and the shape is rectangle.
