9 - 6 + 4 - 8/3 ..,
geometric series a(n) = a1r^(n-1)

r = a(n+1)/a(n)
-6/9 = -2/3
4/-6 = -2/3
-8/3/4 = -2/3
so r = -2/3 and a1 = 9

Sn = a1(1-r^n)/(1-r) = 9(1-(-2/3)^n)/(1-(-2/3))
n is infinite Sn = 9/(5/3) = 27/5

Explain how to use the missing pieces strategy to compare two fractions.include a diagram with your explanation.
umka21 [38]
In order for us to tell whichever fraction is greater than or lesser than, we need to look for the missing part. 

For example,  we have 2/3 and 1/3.
2/3 needs to have 1/3 in order to complete the whole.
1/3 needs to have 2/3 in order to complete the whole.

1/3 < 2/3
<span>So 2/3 is bigger than 1//3</span>

A cylinder has a height of 13 centimeters and a radius of 4 centimeters. What is its volume? Use ​ ≈ 3.14 and round your answer
Roman55 [17]

Answer:

Volume of a cylinder = 653.12 cm³

Step-by-step explanation:

Volume of a cylinder = πr²h

Where,

Height, h = 13 cm

Radius, r = 4 cm

π = 3.14

Volume of a cylinder = πr²h

= 3.14 × (4cm)² × 13 cm

= 3.14 × 16 cm² × 13 cm

= 653.12 cm³

Volume of a cylinder = 653.12 cm³
