$\huge{\underline{\underline{\mathfrak{\purple{answer}}}}}$

Volume of Cylinder

• = pie r^2 h
• 448 = 22/7 × r^2 × 7
• 448 ÷ 22 = r^2
• 20.36 = r^2
• 4.51 = r

T.S.A OF CYLINDER

• = 2pie r ( r + h )
• = 2 × 22/7 × 4.51 ( 4.51 + 7 )
• = 44/7 × 4.51 ( 11.57 )
• = 44/7 × 52.065
• = 114543 / 350
• = 327.26 ( approx )
