Question

PLEASE HELP DUE SOON ONLY Q6 I have the work for the rest.

Answer 1

Given:

Diameter=40 feet

so radius=20 feet(d=2r)

Height of 2nd tank= 130 feet

Required:

Volume of sphere

Volume of cylinder

Step-by-step explanation:

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

`\begin{gathered} (4)/(3)\pi r^3 \\ =(4)/(3)*3.14*20*20*20 \\ =33,493.33feet^3 \end{gathered}`

Then we are going to calculate volume of cylinder=

`\begin{gathered} =\pi r^2h \\ =3.14*20*20*130 \\ 163,280feet^3 \end{gathered}`

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.
