We are given the formula:
V =
Plug in the the radius (3) and volume (127.23):
127.23 = 
Square the 3 :
127.23 = 
Multiply the pi & volume:
127.23 = 28.26h

Answer:1) c. 5,9,13,17,21
2) a. a1=8, an=an-1 -2
Step-by-step explanation: 1) an=4n+1
⇒ a1=4×1+1=5
a2=4×2+1=9
a3=4×3+1=13
a4=4×4+1=17
a5=4×5+1=21
2) clearly a1=8 and then the terms of series are decreasing by 2
so, an=an-1 -2
