<h3>Scott needs to buy 50.24 feet of fencing</h3>

<em><u>Solution:</u></em>

Given that,

Scott wants to buy fencing to place around a circular rock garden

The diameter of the circle is 16 feet

The amount of fencing Scott will need to buy is equal to the circumference of circular garden

<em><u>The circumference of circle is given as:</u></em>

C = \pi d

Where, "d" is the circumference of circle

From given,

d = 16 feet

Therefore,

C = 3.14 \times 16\\\\C = 50.24

Thus, Scott needs to buy 50.24 feet of fencing

an architect is presenting a scale model of a building she's designed to the planning committee of college the scale of the mode
Naddik [55]

The tall of the actual building will be 216 feet

Step-by-step explanation:

An architect is presenting a scale model of a building she's designed

to the planning committee of college

1. The scale of the model is 1 inch = 18 feet

2. The tallest wall in the model is 12 inches

3. We need to know how tall the actual building will be

Let us used the ratio method

∵ The scale of the model is 1 inch represents 18 feet

∵ The tallest wall in the model is 12 inch

→  Model(in)    :    Actual(ft)

→  1                  :    18

→  12                :    h

- By using cross multiplication

∴ 1 × h = 12 × 18

∴ h = 216 feet

∴ The actual height is 216 feet

The tall of the actual building will be 216 feet
