A cylindrical vessel open at the top has radius 7 cm and height 10 cm. Find the area of metal in it, in cm² (the curved surface together with the base). Take π = 22/7.

Question

Accepted Answer

594. Curved surface = 2πrh = 2 × (22/7) × 7 × 10 = 440 cm². Base = πr² = (22/7) × 49 = 154 cm². As there is no lid, the metal used = 440 + 154 = 594 cm².

A cylindrical vessel open at the top has radius 7 cm and height 10 cm. Find the area of metal in it, in $cm^{2}$ (the curved surface together with the base). Take π = 22/7.
