Carton length = diameter× 6 = 6× 6 = 36 cm

Carton width = diameter× 4 = 6× 4 = 24cm.

Carton height = cylinder height = 10 cm.

At least cardboard is needed.

=2×(36×24+36× 10+24× 10)

=2928 square centimeters

Question 2:

1/3x3. 14x5？ x 15 \u( 3. 14x 10？ )= 1.25cm

Question 3:

3.14x01x15x60x10 = 282,600 square meters =282.6 square decimeters.

Question 4:

(11× 2) × (11× 2 )× 44 = 21296 (cubic millimeter) =2 1.296 (cubic centimeter).
