How do you do this question?

Step-by-step explanation:

lim(n→∞) an / bn

= lim(n→∞) [(sin²n) / (n³√n + n)] / (1 / n^⁷/₂)

= lim(n→∞) [(sin²n) / (n³√n)] / (1 / n^⁷/₂)

= lim(n→∞) (sin²n)

DNE

Since the limit does not exist, the limit comparison test is inconclusive.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
