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.
