Question

A metallic cylindrical pipe has a thickness 0.5 cm. and outside radius
2.25 cm. If 1 cubic centimetre of the metal has mass 8 grams,find the mass
of 35 cm long pipe.

Answer 1

Answer:

Therefore the mass of the pipe =4125 gram

Step-by-step explanation:

Step-by-step explanation:

Given metallic cylindrical pipe has thickness 0.25 cm and outside radius(R) 3.25 cm and height(h)=70 cm

The inside radius(r) = (3.25-.25)cm =3 cm

The volume of metallic cylinder =

                                                   

                                                    =343.75

Given that 1

= 12 g

Therefore the mass of the pipe =( 343.75× 12) g =4125 gram
