Hello from MrBillDoesMath!
Answer:
3.14
Discussion:
C = circumference, r = radius, d = diameter = 2 r
For a circle, C = 2 Pi r = d Pi
Substituting the values in the question gives
C = d Pi
28.26 = 9 Pi => divide both sides by 9
Pi = 28.26/9 = 3.14
Thank you,
MrB
=2/3 x 4 1/5
Change 4 1/5 to improper fraction
=2/3 x 21/5
Multiply the two numerators together and multiply the two denominators together
= (2*21)/(3*5)
=42/15
Convert back to mixed fraction
= 2 12/15
Simplify by dividing 3 into top & bottom
ANSWER:
= 2 4/5 simplest mixed fraction
Hope this helps! :)
