Question

how much will a metallic cylinder of radius 14m and height 3.5m cost if the metal used for making the cylinder is rs.100 per cubic metre​

Answer 1

Cost of Cylinder = 215600 Rs

Explanation:

Radius = 14m

Height = 3.5 m

Cost of metal/ cubic meter= 100 rs

Volume of Cylinder =
`\pi *r^(2) *h`

Volume of Cylinder =
`(22)/(7) *14^(2) *3.5`

Volume of Cylinder= 2156 m³

Cost of Cylinder = Volume of cylinder * cost of metal/ cubic meter

Cost of Cylinder =
`2156 * 100 = 215600` Rs
