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

Because:

Volume of a cylinder = πr²h

V = 22/7 x 4 x 4 x 20

V = 1,005.7

answer: the correct one is a

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
