The fencing required to enclose a circular garden whose radius is 22 m is 138.16 m.
Further Explanation
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
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.
In this case;
The radius of the circle = 22 m
π = 3.14
But;
Circumference of a circle is given by 2πr
Thus;
Circumference = 2 × 3.14 × 22 m
= 138.12 m
