Question

Someone please help me with this.

The volume of a cylinder is 231 m^3.
Find the height, in m, of the cylinder if the radius is 0.7 m.​

Answer 1

• Radius=r=0.7m
• Volume=231m^3
• Height=h

`\boxed{\sf Volume=\pi r^2h}`

`\\ \sf\longmapsto π(0.7)^2h=231`

`\\ \sf\longmapsto 0.49πh=231`

`\\ \sf\longmapsto πh=(231)/(0.49)`

`\\ \sf\longmapsto 3.14h=471.4`

`\\ \sf\longmapsto h=(471.4)/(3.14)`

`\\ \sf\longmapsto h=150m`
