The area of an Equilateral triangle is given by the formula A= 3pi squared/4(s)Squared. Which formula represents the length of e
ad-work [718]

Answer:

The formula that represents the length of an equilateral triangle’s side (s) in terms of the triangle's area (A) is \text{s}= \sqrt{ \frac{4 \text{A}}{\sqrt{3} }} .

Step-by-step explanation:

We are given the area of an Equilateral triangle which is A = \frac{\sqrt{3} }{4} \times \text{s}^{2} . And we have to represent the length of an equilateral triangle’s side (s) in terms of the triangle's area (A).

So, the area of an equilateral triangle =  \frac{\sqrt{3} }{4} \times \text{s}^{2}

where, s = side of an equilateral triangle

A  =  \frac{\sqrt{3} }{4} \times \text{s}^{2}

Cross multiplying the fractions we get;

4 \times A = \sqrt{3} \times \text{s}^{2}

\sqrt{3} \times \text{s}^{2}= 4\text{A}

Now. moving \sqrt{3} to the right side of the equation;

\text{s}^{2}= \frac{4 \text{A}}{\sqrt{3} }

Taking square root both sides we get;

\sqrt{\text{s}^{2}} = \sqrt{ \frac{4 \text{A}}{\sqrt{3} }}

\text{s}= \sqrt{ \frac{4 \text{A}}{\sqrt{3} }}

Hence, this formula represents the length of an equilateral triangle’s side (s) in terms of the triangle's area (A).

Answer:

area = 50.27 sq inches

circumference = 25.14 in

Step-by-step explanation:

given radius r = 4 in

area = πr² = 3.142 x 4² = 50.27 square inches

circumference = 2πr = 2 x 3.142 x 4 = 25.14 inches
