Is this very good or...okay?

For the price it's good. If you actually have expensive knives and are serious spend more and get better quality. It's like discount clothing detergent or Tide. Both work, one much better, you decide what better is worth

What is the diameter of the 12-inch rod?

Well, assuming we know the mass and the density of the rod, we automatically have the volume of the rod. Also, in order to know the diameter, you must have the height. Or you can’t, if you want to express the answer on it’s terms. Remember the formula density=(volume/mass) . Just clear for volume. Well, now having the volume of the rod, we must specify that we assume it’s a cylinder. Otherwise, the problem will be a little bit more difficult to resolve. Ok, now recall the formula of the volume of a cylinder. V=πr2h . As you see, the volume includes the radius of the rod and the height. Also, remember that r=d/2 so you can replace it on the formula. V=π(d/2)2h V=π(d2/4)h And as you want to calculate what is the diameter, we clear it for him. d2=4V/πh d=√(4V/π∗h).
