How much fencing is required to enclose a circular garden whose diameter is 287m?

Step-by-step explanation:

Enclosing something with fencing is a perimeter thing.  Since we are dealing with a circle, we need the circumference instead, which is the same thing, different formula.

Filling in with the diameter of 287 m:

 or you could just say that the circumference is

287π.  If you have to multiply in π, then the circumference is

901.18 m

The answer to your question is 901.2 m

Step-by-step explanation:

Data

Perimeter = ?

diameter = 287 m

Process

1.- Calculate the radius of the garden

    radius = diameter/2

-Substitution

   radius = 287/2

-Result

   radius = 143.5 m

2.- Calculate the perimeter

Perimeter = 2πr

-Substitution

Perimeter = 2(3.14)(143.5)

-Simplification and result

Perimeter = 901.18 ≈ 901.2 m
