Distance around the outside of the pit

= 3π feet = about 9.42 feet

How much space needs to be covered inside the pit

= 2.25π feet = about 7.07 feet

Step-by-step explanation:

Let's get the radius first so we can use it later.

Radius:

diameter = 2radius

3 = 2r

r = 3/2 ft

The distance around the outside of the pit is also known as the circumference. Let's find that next.

Circumference:

C = 2πr

   = 2π(3/2)

   = 3π feet = about 9.42 feet

How much space needs to be covered inside the pit is another way to ask for area, so let's do that now.

Area:

A = πr^2

   = π(3/2)^2

   = 2.25π feet = about 7.07 feet
