Answer 2

Answer:

curved surface area 2112 cm^2 , total surface area 800π cm^2

Step-by-step explanation:

If h be height of a cylinder and r be base radius of a cylinder

then curved surface of a cylinder be 2πr × h cm^2

and total surface area of the cylinder be 2πr (r + h) cm^2

given that

height of the cylinder , h = 42 cm

radius of the cylinder , r = 8 cm

curved surface area , 2 π r h = 2 × 22/7 × 8 × 42 = 2 × 22 × 8 × 6

= 2112 cm^2

total surface area = 2πr(r + h) = 2× 22/7 × 8 × (8+42) = 800π cm^2
