Answer:
From the figure we can observed that 1 round of wire will cover 3 mm height of cylinder.
Number of rounds =
Diameter of wire
Height of cylinder
=
0.3
12
=40 rounds.
Length of wire required in 1 round = Circumference of base of cylinder
=2πr=2π5=10π
Length of wire in 40 rounds =40×10π
=
7
400×22
=
7
8800
=1257.14 cm
=12.57 m
Radius of wire =
2
0.3
=0.15 cm.
Volume of wire = Area of cross-section of wire x Length of wire
=π(0.15)
2
×1257.14
=88.898 cm
3
Mass = Volume x Density
=88.898×8.88
=789.41 gm
