Question

How much will a metallic cylinder of radius 14m and height 3.5m, cost if the metal used in making this cylinder is rupees 100 per cubic meters? ​

Answer 1

Answer:

₹109955.74

Step-by-step explanation:

volume of a cylinder=(22/7) x (r^2) x h

                                 =(22/7)x14x14x3.5 cubic meters

                                 =1099.5574 cubic meters

cost of metal required=₹100 x volume of cylinder

                                    =₹109955.74

Answer 2

Its cost would be 215600 rupees

Step-by-step explanation:

Given,

The radius of the cylinder, r = 14 m,

Its height, h = 3.5 m,

So, the volume of the cylinder,

$V=\pi r^2 h$

$=\frac{22}{7}\times 14\times 14\times 3.5$

$=22\times 2\times 14\times 3.5$

= 2156 m³

Since, the cost for 1 cubic meter = 100 rupees

So, the cost for 2156 m³ = 2156 × 100 = 215600 rupees
