The height of the actual steeple is 54 feet
What is dilation?
Dilation involves enlarging or reducing the side length of a shape to create another shape by a constant scale factor, where the scale factor does not equal one.
How to determine the actual height of the steeple?
The given parameters are:
Scale factor = 1 : 18
This can be rewritten as:
Scale height : Actual Height = 1 : 18
The height of the scale model is given as:
Scale height = 3 feet
So, we have:
3 ft : Actual Height = 1 : 18
Express as fraction
Actual Height/3 = 18/1
Multiply both sides by 3
Actual Height = 54
Hence, the height of the actual steeple is 54 feet
