Answer:

21 caps

Step-by-step explanation:

Dimensions of Colonical caps

Radius = 3cm

Height = 4cm

Slant height of cone(l) = √h^2+r^2

= √(4) + (3)^2

= √16+9

= √25

= 5 cm

Lateral surface area of Colonical caps = πrl

= πrl

= 22×3×5 /7

= 22×15/7

= 330/7 cm^2

Now

Number of caps that can formed with

1000^2cm paper sheet = 1000/(330/7)

= 1000×7/330

= 3.03 × 7

= 21.21

The number of caps should be a whole number therefore 21 caps can be formed

with 1000 cm^2 paper sheet.

Hope it helps.
