<u>Formula</u>

<em>An expression that uses variables to state a rule is a </em><u><em>formula</em></u>

<h2>Explanation:</h2>

An expression that uses variables to state a rule is a formula. It's important to know that formulas uses the equals sign (=) and includes two or more variables. Formulas gives us information that we express symbolically. For example, the well known formula for the volume of a sphere is defined as:

$V=\frac{4}{3} \pi r^3 \\ \\ \\ Where: \\ \\ V:Volume \ of \ the \ sphere \\ \\ r:Radius \ of \ the \ sphere$

So in this formula we have a relationship between the volume of a sphere and its radius, so if we have information about the radius of it we can easily calculate the volume of it.

What is the cost of constructing a fence 6 feet, 6 inches, high around a lot measuring 90 feet by 175 feet, if the cost of erect

boyakko [2]

Answer:

The total cost is $3,504.63

Step-by-step explanation:

Length of fence = 90 feet

Breadth of fence = 175 feet

Height of fence = 6 feet, 6 inches

1 inch = 0.0833333 feet

6 inches = 6*0.0833333 =0.4999998 feet

So, Height of fence = 6 feet + 0.49 feet =6.49 feet ≈ 6.5 feet

Perimeter = $2(Length \times breadth)=2(90 +175) = 530 feet$

Cost of erecting the fence is $1.25 per linear foot

So, Cost of erecting the fence in 530 feet = $530 \times 1.25 = 662.5$

Total surface area = $2(length +breadth) Height =530 \times 6.5=3445ft^2$

The cost of materials is $0.825 per square foot of fence

Cost of material for 3445 sq.feet = $3445 \times 0.825 =2837.7525$

So, total cost = 2842.125+662.5 = 3504.63

Hence The total cost is $3,504.63
