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.
