Question

A cylinder has a height of 5 meters and a radius of 4 meters. What is its volume? Use ​ ≈ 3.14 and round your answer to the nearest hundredth.

Answer 1

Given:-

• 
  `\rm{height = 5m}`

`\:`

• 
  `\rm \: radius = 4m`

`\:`

• 
  `\rm \: π ( pi ) = 3.14`

`\:`

By using formula:-

`\boxed{ \mathrm{volume \: of \: cylinder = πr²h}}`

Solution:-

`\rm \: v = πr²h \\ \rm \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: v = 3.14×( 4 )² × 5 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \rm \: v = 3.14 × 16 × 5 \\ \rm \: \: \: \: \: \: \: \: \: \: v = 3.14 × 80 \\ \: \: \: \:\boxed{ \rm \color{hotpink}{v = 251.2 }}`
