Question

Help me pleaseee >:)

Answer 1

Cylinder:
`V_c = 80 \pi \approx 251.33`

Rectangular prism:
`V_r = 384`

Total:
`V = 80\pi + 384 \approx 635.33`

Explanation:

The volume of the cylinder:

`V_c = \pi r^2 h\\V_c =\pi4^2 * 5\\V_c = 80\pi\\V_c \approx 251.33`

The volume of the rectangular prism:

`V_r = lwh\\V_r = 12 * 8 * 4\\V_r = 384`

The total volume:

`V = V_c + V_r\\V = 80\pi + 384\\V \approx 635.33`
