1.	A man donates 10 aluminum buckets to an orphanage. A bucket made of aluminum isof height 20 cm and has its upper and lowest ends of radius 36 cm and 21 cnmrespectively. Find the cost of preparing 10 buckets if the cost of aluminum sheet is42 per 100 cm2. Write your comments on the act of the man30/2
Answer» i also want this answer Surface area of bucket = π(r1 + r2)l + πr1² l = √[h² + (r1 - r2)²] = √[20² + (36 - 21)²] = √625 = 25 cm ∴ Surface area of 1 bucket = 22/7 × 1866 cm2 Surface area of 10 buckets = 22/7 × 18660 cm2 Cost of aluminium sheet = Rs. 24631.20 The man is kind-hearted and values others needs.

Surface area of bucket = π(r1 + r2)l + πr1²

l = √[h² + (r1 - r2)²]

= √[20² + (36 - 21)²]

= √625

= 25 cm

∴ Surface area of 1 bucket = 22/7 × 1866 cm2

Surface area of 10 buckets = 22/7 × 18660 cm2

Cost of aluminium sheet = Rs. 24631.20

The man is kind-hearted and values others needs.
