Question

How much fencing is required to enclose a circular garden whose radius is 22m? Use 3.14 for pi

Answer 1

Circumference = πd
22*2 = 44
44*3.14 = 138.16

Answer 2

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
