Francisco is making an effort to drink more water, and has set a goal of 222 liters per day. He wants to know the volume of the water bottle he takes to school each day. The water bottle has the dimensions shown in the diagram.

Radius 4

Height 20 What is the volume of Francisco's water bottle?

V = 1,005.7 rounded off to one decimal place

Step-by-step explanation:

Volume of a cylinder = πr²h

V = 22/7 x 4 x 4 x 20

V = 1,005.7

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
