Ha I read that earlier.
Thank you.

So none.
If you know the diameter cut it in half to get the radius.
Or
If you know the circles circumference divide it by 2pi.
$${\mathtt{7}}{\mathtt{\,\times\,}}{\left(-{\mathtt{1}}\right)}^{{\mathtt{2}}}{\mathtt{\,-\,}}{\mathtt{3}}{\mathtt{\,\times\,}}\left(-{\mathtt{1}}\right) = {\mathtt{10}}$$
Umm. Gross. We don't need to know.
$${\frac{{\mathtt{6}}}{{\mathtt{5}}}}{\mathtt{\,\times\,}}-{\mathtt{3}} = {\mathtt{\,-\,}}{\frac{{\mathtt{18}}}{{\mathtt{5}}}} = -{\mathtt{3.6}}$$
Your welcome. Though I can't help with your other question I was never any good at that and still not. Haha
A. I believe. Both -5 and -4.6 are smaller than -4.
I was a little late on my reply. Haha.
