Answer:
A.) The red cylinder.
Step-by-step explanation:
For a cylinder:
V = (1/3)(pi)r^2h
Red:
V = (1/3)(pi)(2^2)(4) = 16pi/3
Blue:
V = (1/3)(pi)(1^1)(8) = 8pi/3
Since 16pi/3 is greater than 8pi/3, the red cylinder has a greater volume.
Answer:
r = - 3
Step-by-step explanation:
To find the common ratio r, divide consecutive terms
- 9 ÷ 3 = - 3
27 ÷ - 9 = - 3
- 81 ÷ 27 = - 3
Thus common ratio = - 3
