Question

Sam made a model of the Liberty Bell with a

base circumference of 8 inches. If the base
crcumference of the actual Liberty Bell is 12
feet, what scale did he use?

Answer 1

1 : 18

When finding scale factor, both measurements should in same unit

Circumference of the model bell = 8 inches

1 feet = 12 inches

12 feet = 12 * 12 = 144 inches

Circumference of the actual bell = 12feet = 144 inches

Model : Actual = 8 : 144

= 8÷8 : 144÷8

= 1 : 18
