I think it’s 0.85d, but i’m not sure
The answer is -2.
im sorry if the work is messy.
0.35 is rounded to the nearest hundredth 3would be in the tenth place 4is in the hundredth place 6is in the thousandths place hope this helps
If you divide the circumference C over the radius r, you get 2pi
2pi = C/r
this is because
C = 2pi*r
is one formula to find the circumference. Another formula is
C = pi*d
which works because d = 2r, ie the diameter is twice the radius.
