Answer» Answer: = 69.12cm² Step-by-step explanation: Given, volume of the cylinder(v) = 44cm³ radius (R) = 2cm from FORMULA of volume, v = πr²h or, 44 = 3.14 × 2²×H or, 44 = 12.56 × h or, 44/12.56 = h ∴ h = 3.50cm To find: TOTAL surface area (TAS)= ? from formula, TSA = 2πr (r+h) or, = 2× 3.14 × 2 (2+ 3.50) = 12.56 × 5.50 ∴ = 69.12cm² |
