Q: What is the mass of a solid iron wrecking ball of radius 18cm?
TWO questions, the paper that has this problem has a substances and densities chart, it has Iron as 7.8 x 103...when doing the formula below, I used 7800...should I be using 7.8 instead?
Ex. D = M/V D = 7800 so nwo I have 7800 = M/V
V = 4/3 * 3.14 * (18)3 = 24429
Now I have
7800 = M/24429
I would multiple 24429 by 7800 and get 190546200...so clearly that can't be correct? I have to use 0.18m instead of 18cm, yes?

I hope it will mark me brainliest.
