Answer: b = 34/5
Step-by-step explanation:
Answer:
C is the answer
b.) because it is over 90*
1.257 gram
Hope thus helped!
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.
