Question

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

Answer 1

Step-by-step explanation:

Given:

h=3.5 m

r=14m

vol of cylinder=πr^2h

=2156m^3

now, 100per cu.m

per 1 cu.m=2156x100

=215600/-

Answer 2

Answer:

Here goes the answer--=₹109955.74

Step-by-step explanation:

Because:

         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
