height of the cylinder​

Answer 1

Answer

a cuboid shaped slab of iron whose dimensions are 55 cm by 40 cm by 15 cm is melted and recasted into a pipe. the outer radius and thickness of the pipe are 4 cm and 1 cm respectively. find the lenght of the pip

Length of pipe = 15 m

Step-by-step explanation:

a cuboid shaped slab of iron whose dimensions are 55 cm by 40 cm by 15 cm is melted and recasted into a pipe

Volume of Slab = 55 * 40 * 15

= 33000 cm³

Outer radius of the pipe are 4 cm

Thickness of the pipe = 1 cm

Inner Radius = 4 - 1 = 3 cm

Height of pipe = h cm

Volume of Material used in pipe = π (4² - 3²) h

= (22/7)*7 * h

= 22h

22h = 33000

=> h = 1500 cm

1m = 100 cm

=> h = 15 m

Length of pie = 15
