mark as brainliest please
Step-by-step explanation:
Height of cylinder = 15 cm
And,
Radius of cylinder = 7 cm
Curved surface area of cylinder = 2πrH
=> 2 × 22/7 × 7 × 15
=> ( 2 × 22 × 15 ) cm².
=> 660 cm .
And,
Total surface area of cylinder = 2πr ( r + h )
=> 2 × 22/7 × 7 ( 7 + 15 )
=> ( 44 × 22 ) cm².
=> 968 cm².
