Question

a solid iron rod has a cylinderical shape.its height is 11 CM. and base diameter is 7cm then find the total volume of 50rods​

Answer 1

Answer: 21175 cm3

Step-by-step explanation:

First find the volume of each

V = π*(diameter/2)^2 * height

Then multiply V by 50(number of items)

Answer 2

Answer:

=21175cm²

Step-by-step explanation:

height (h)=11cm

diameter(d)=7cm

radius(r)=d/2=3.5cm

volume of 1 cylindrical rod=r^2h(pie)

                                            =3.5*3.5*11*22/7

                                            =423.5cm²

volume of 50 cylindrical rod=50*volume of 1 cylindrical rod

                                           =50*423.5

                                           =21175cm²
