How many pipes of length 30 cm and radius 3.5 cm can be made from an
aluminum sheet of length 6.6 m and breadth 1.5 m
Answers
Answer:
165 pipes
Step-by-step explanation:
Length of aluminum sheet = 6.6m
= 6.6 *100
= 660cm
breadth of aluminum sheet = 1.5 m
= 1.5 *100
= 150 cm
area of aluminum sheet = l*b
660*150
99000cm^2
Length of pipes = 30cm
radius of pipe = 3.5cm
Surface area = 2πr*h
= 2 * 22/7 * 35/10 * 30
= 600cm^2
Number of pipes = Area of aluminum sheet/ area of a pipe
= 99000/600
= 165
