Question

A cylindrical drinks bottle has a paper label wrapped around the outside. The label has a height of 7cm and the bottle has a radius of 3cm. The label also has a 1.5cm overlap so that it can be stuck together and held into place. Calculate the area of the label.​

Answer 1

Answer:

142.4999999997

Step-by-step explanation:

For Cylindrical bottle:

r = 3cm

Circumference of a circle =

$2\pi r$

Circumference of Cylindrical bottle = 2 × (22/7) × 3

= 132 / 7

= 18.8571428571

For Label:

height = 7 cm

P.S: here height means breadth as the label is rectangular in shape

length = 18.8571428571 + 1.5

= 20.3571428571

P.S.: as it overlaps by 1.5 cm

Area = length × breadth

= 20.3571428571 × 7

= 142.4999999997 cm
