!!Here's your answer.. ⬇⬇_____________________

!!Here's your answer.. ⬇⬇_____________________Radius of cylinder ( r ) = 7 cm

!!Here's your answer.. ⬇⬇_____________________Radius of cylinder ( r ) = 7 cmHeight of cylinder ( h ) = 15 cm

!!Here's your answer.. ⬇⬇_____________________Radius of cylinder ( r ) = 7 cmHeight of cylinder ( h ) = 15 cmC.S.A = πr²h

!!Here's your answer.. ⬇⬇_____________________Radius of cylinder ( r ) = 7 cmHeight of cylinder ( h ) = 15 cmC.S.A = πr²h= 22/7 × 7 × 7 × 15

!!Here's your answer.. ⬇⬇_____________________Radius of cylinder ( r ) = 7 cmHeight of cylinder ( h ) = 15 cmC.S.A = πr²h= 22/7 × 7 × 7 × 15= 2310 cm²
