Question

The circumference of a circle is the distance around the circle, while

the area of a circle is the amount of space contained inside the

circle. When solving problems involving circles, it is important to

think about what you are trying to determine.

1. A city park has a large circular garden with a path around it.

The diameter of the garden is 60 feet.

a. Gina likes to walk along the circular path during her lunch

breaks. How far does Gina walk if she completes one

rotation around the path?

Answer 1

Approximately 189 feet

Explanation:

A complete one rotation around the path is the circumference of the garden.

Given that the diameter of the garden = 60 feet.

The circumference of a circle = 2
`\pi`r

where r is the radius.

So that:

r =
`(diameter)/(2)`

=
`(60)/(2)` = 30 feet

The distance covered by Gina in one rotation around the path = 2
`\pi`r

= 2 x
`(22)/(7)` x 30

=
`(1320)/(7)`

= 188.57

≅ 189 feet

Therefore, Gina covered a distance of approximately 189 feet around the path.
