C = pi×diameter OR C = 2pi×radius
So...
17.8 = pi×diameter 17.8 = 2pi×radius
17.8/pi = diameter 17.8/2pi = radius
<span>5.66591597407 = diameter or d
</span><span>2.83295798704 = radius or r</span>
The best answer is 15/8 and it could be simplified I think
there are 16 ounces in a pound so 16x7=112 +2= 114
