Acylindrical pop can us 12.5 cenimeters tall and 5.5 centimeters wide. what is the volume of the pop can

The width is basically the diameter:
Given 
Diameter = 5.5 cm
So Radius =  =  = 2.75 cm
Height of cylinder = 12.5 cm

Formula of the volume of a cylinder
V = Area of base × height of prism
    = r² × h
    =(2.75)² () × 12.5
    =7.5625 × 12.5
    ≈ 296.83 cm³

The coordinates of point a right now is (-3,-1) you have to multiply these coordinates by a factor of 2 to get (-6,-2)
