1. 30π in³

2. 60π in³

3. 90π in³

4. 300π in³

Answer 1

Given:-

• 
  `\rm{radius= \bold{ 3}}`

• 
  `\rm{height = \bold{ 10}}`

`\:`

To find:-

• 
  `\rm{volume \: of \: the \: cylinder = \: ?}`

`\:`

By using formula:-

• 
  `\underline{ \boxed{ \rm{ \red{volume \: of \: the \: cylinder = πr²h}}}}`

`\:`

Solution:-

• 
  `\rm{v = πr²h}`

`\:`

• 
  `\rm{v = π×( 3 )² × 10}`

`\:`

• 
  `\underline{\boxed{ \color{purple}{\rm{v = 90π in³}}}}`

`\:`

The volume of the cylinder is 90π in³
