Question

50 coins of thickness 0.14 cm and radius 1 cm are piled up one above the other find the volume of cylinder does of thus obtained

Answer 1

Dear Student,

◆ Answer -

V = 22 cm^3

● Explanation -

# Given -

r = 1 cm

t = 0.14 cm

n = 50 coins

# Solution -

Total height of the cylinder is -

h = nt

h = 50 × 0.14

h = 7 cm

Volume of the cylinder is given by -

V = πr²h

V = 22/7 × 1^2 × 7

V = 22 cm^3

Hence, Volume of the cylinder is 22 cm^3.

Thanks dear. Hope this helps you...
