Question

PLEASE HELP I GIVE THANKS

Answer 1

Let's plug the given value is in the formula :
`{ V }_( cylinder )=\quad \pi { r }^( 2 )h`

First cylinder :
`{ V }_( cylinder1 )=\quad \pi { 8 }^( 2 )21=\pi \cdot 64\cdot 21=1344\pi \quad { cm }^( 3 )`

Second cylinder :
`{ V }_( cylinder2 )=\quad \pi { 11 }^( 2 )45=\pi \cdot 121\cdot 45=5445\pi \quad { cm }^( 3 )`


`5445-1344=4101\\ \\ 4101\pi \quad { cm }^( 3 )`

Answer is D
