Answer:
a cone with a base circumference of about 126 mm
Step-by-step explanation:
Rotating a triangle about a line results in a cone created by the rotation. This is because the segment at the bottom forms a circle, and the point at the top stays there; the three-dimensional figure with a circular base and a point at the top is a cone.
Since we rotate the segments about a line, this makes the length of the base the radius of the circle. This means the circumference would be
C = 2πr = 2(3.14)(20) = 125.6 ≈ 126 mm

Answer: NiCl2 + Fe
Iron is above nickel in the activity series, so iron will replace nickel like this:
NiCl2 + Fe → FeCl2 + Ni
Cu(OH)2 is insoluble, so it will form a precipitate.
