Answer:
volume is 1570 cm³
mass is 12560 g
Step-by-step explanation:
1m = 100 cm
the volume is :
1/4 x [tex]\pi[/tex] x 6² x 100 - 1/4 x [tex]\pi[/tex] x 4² x 100
= 900 [tex]\pi[/tex] - 400 [tex]\pi[/tex] { v = 1/4 [tex]\pi[/tex] d²h }
= 500 [tex]\pi[/tex]
= 500 x 3.14
= 1570 cm³
the mass of the pipe is:
1570 x 8 = 12560 grams
