Question

Yolanda is planning to put a pool in her backyard. The scaled model below gives the reduced measures for diameter and depth.


The diameter of a pool is 18 centimeters and the depth is 4 centimeters.

Not drawn to scale


The yard space is large enough to have a pool that has a diameter of 27 feet. If Yolanda wants to keep the pool in proportion to the model, what will be the depth of the pool?

4.5 feet

5 feet

6 feet

6.75 feet

Answer 1

We can make a proportion:

$\frac{18 cm} {4 cm} = \frac {27 ft} {x},$

x = 6 feet.

So, the correct answer is 6 feet.
