Question

grapes were paked in cylinder cans each cans 13cm high and 8cm diameter. How many square centimeters of paper are in the lable which covers the total letral surface of the can ?Take π=3.14.​

Answer 1

total lateral surface area = 2πr(h+r)

= 2× 3.14×4(13+4)

= 427.04 square cm

Answer 2

653.12 square centimeters of paper are in the lable which covers the total lateral surface of the can

Step-by-step explanation:

Height of cylindrical can = 13 cm

Diameter of cylindrical can = 8 cm

Radius of cylindrical can = $\frac{8}{2} = 4 cm$

Curved surface area of cylindrical can= $2 \pi r h = 2 \times 3.14 \times 8 \times 13 = 653.12 cm^2$

Hence 653.12 square centimeters of paper are in the lable which covers the total lateral surface of the can
