Question

A small water silo has a diameter of 30 feet and a height of 60 feet. The clay model the engineers used only has a height of 10 inches with proportional volume. Determine the diameter of the model

Answer 1

Diameter of clay model = 5 inches

Explanation:

Given:

Diameter of silo = 30 feet

Height of silo = 60 feet

Height of clay model = 10 inches

Find:

Diameter of clay model = ?

Computation:

Note:

WE know that

⇒ [Diameter of silo / Height of silo] = [Diameter of clay model / Height of clay model]

⇒ [30 / 60] = [Diameter of clay model / 10]

⇒ [1 / 2] 10 = [Diameter of clay model]

⇒ Diameter of clay model = 5 inches
