A solid metallic cylinder of base radius 3 cm and height 5 cm is melted to form cones, each of height 1 cm and base radius 1 mm. The number of cones is?

Q: A solid metallic cylinder of base radius 3 cm and height 5 cm is melted to form cones, each of height 1 cm and base radius 1 mm. The number of cones is?

Let required number of coins be n, Then, n x 1/3 x π (1/10)2 x 1 = π x (3)2 x 5 ∴ n = 9 x 5 x 3 x 100 = 13500

7500
13500
3500
4500

Correct Answer: 13500

Explanation:

Let required number of coins be n, Then,
n x 1/3 x π (1/10)² x 1 = π x (3)² x 5
∴ n = 9 x 5 x 3 x 100 = 13500
