The scale factor of the model car to the actual car is 1:16

a) What is the height of the car if the height of the model is 5.5in?
1/16=5.5/x
x=88in

b) Each tire of the model has a surface area of 12.9 square inches. What is the surface area of each tire of the actual car?
12.9/x=1/256
x=3302.4in

c) What is the volume of the actual car's engine if the model's engine has a volume of 2 cubic inches?
2/x=1/4096
x=8192in
