Question

Find the circumference given the area = 50.3 m². Use 3.14 for π as necessary.

Answer 1

The circumference of a circle with an area of 50.3 m² is 25.12 m.

Further Explanation

Area

• Area is a measure of how much space is occupied by a given shape.
• Area of a substance is determined by the type of shape in question.

For example;

• Area of a rectangle is given by; Length multiplied by width
• Area of a triangle = 1/2 x base x height
• Area of a circle = πr². where r is the radius of a circle,
• Area of a square = S², Where s is the side of the square.etc.

Perimeter

• Perimeter is defined as the distance along a two dimension shape. Perimeter of different shapes is given by different formulas

For example;

• The perimeter of a rectangle = 2(length+width)
• The perimeter of a triangle = a+b+c; where a, b and c are the sides of the triangle. etc.
• The Circumference of a circle = 2πr , where r is the radius of the circle

In this case;

The Area of a circle = 50.3 m²

π = 3.14

But; Area of a circle = πr²

Therefore;

3.14r²= 50.3 m²

r² = 50.3/3.14

   =16.019

r = √16.019

 = 4.0023

 ≈ 4.00

But;

Circumference of a circle is given by 2πr

Thus;

Circumference = 2 × 3.14 × 4.00

                          = 25.12 m

Answer 2

The answer would be 25.14

C=2 √ π•50.3

Convert into a fraction

C=2 √ π•503/10

Calculate the product

C=2 √ 503 π/10

Use radical rules

C=2 √ 503 π/√ 10

Calculate the product

C= 25.14
