Answer 1

100 Silver Papers required , Paper required for 1000 Chocolates = 33900 cm²

Step-by-step explanation:

A silver paper covers a packet of 10 chocolate coins of radius 2 cm and thickness 7 mm

Paper required for 1 Chocolates  = 2πr(r + h)

r = 2 cm

h = 7mm = 0.7 cm

π = 3.14

Paper required for 1 Chocolates  = 2 * (3.14) * 2 ( 2 + 0.7)

= 33.9 cm²

Paper required for 1 Chocolates = 33.9 cm²

Paper required for 1000 Chocolates = 33900 cm²
