Answer:
Sₙ=3(1/2^n)
Step-by-step explanation:
Notice that in the given series that each term is being multiplied by 1/2, which is our common ratio. 3/2 is the first term because 3*1/2=3/2, so the expression that defines Sₙ is Sₙ=3(1/2^n)
Step-by-step explanation:
circumference =pi × diameter
=(22/7)×2.2
=6.914ft
1/2 is bigger because 1/4 is half of half.
