The radius is 12 so the diameter is 24.
Substitution is best to use one one or both equations is already solved for one of the variables. Elimitation can be use if all variables have a coefficient other than 1.
The answer is A.5% i am not 100% sure thooooo
A can is a cylinder shape.
Volume of a cylinder = PI x r^2 X h
r is the radius and h is the height.
The diameter is given as 3.8, the radius is half that: 3.8 /2 = 1.9
Height is given as 6.5
Volume = 3.14 x 1.9^2 x 6.
Volume = 73.6801 cubic inches.
Rounded to the nearest tenth = 73.7 cubic inches.
