विकल्प

• 4950 cm²

• 4951 cm²

• 4952 cm²

• 4953 cm²

Answer 1

The radii of the top and bottom of a bucket of slant height 45cm are 28cm and 7 cm respectively. The curved surface area of the bucket is 4950 cm².

Explanation:

Curved Surface area of the bucket = π (R + r) l

⇒ Curved surface area of the bucket = π (28 + 7) × 45

⇒ Curved surface area of the bucket = 4950 cm²
