Question

Calculate the curved surface area of a cone whose length is 8cm and base radius is 5cm​

Answer 1

Given:-

• 
  `\tt \: Length = 8cn`

`\:`

• 
  `\tt \: Radius = 5cm`

`\:`

To find:-

• 
  `\tt \: Curved \: surface \: area \: of \: cone = \: ?`

`\:`

By using formula:-

• 
  `\boxed{ \tt \purple{ \: CSA = πrl \: }}`

`\:`

Solution:-

• 
  `\tt \: CSA = πrl`

`\:`

• 
  `\tt \: CSA = π×5×8`

`\:`

• 
  `\tt \: CSA = π×40`

`\:`

• 
  `\underline { \boxed{ \tt \color{lightgray}CSA = 40π}}`

`\:`

hope it helps! :)
