The circumference of a circle is equal to C=2πr
From the question, we have 615.44.
Assume that pi is equal to 3.14
Substitute and solve for r
615.44= 2(3.14)r
r= 615.44/ 6.28
r=98.4704
r=98
Therefore, the radius is about 98 units.
To check:
C=2πr
C=2 x 3.14 x 98
C=6.28 x98
C=615.44
I think it talks about if this is a one to one function or not
3/8x=6.
x=6*8/3.
x=2*8.
x=16.

Answer: -13, -17, -21
Explanation: Subtract 4 from each term. Do this for 3 terms
1kg is 2.20462 pounds
So 4kgs are 8.81849
Divided by $16 would equal 0.551155625
Therefore Each pound will cost 0.551155625
