1

3

of a cylindrical tin whose

radius is 3cm and height 7 cm.​

Answer 1

Answer:

Step-by-step explanation:

For cylindrical part:        Radius (r) = 7 cm        Height (h) = 6 cm        ∴ Curved surface area               = 2πrh                       For hemispherical part:               Radius (r) = 7 cm        ∴ Surface area = 2πr2                       ∴ Total surface area               = (264 + 308) cm2 = 572 cm2.
