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?

Approximately 189 feet

Step-by-step 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 = 2r

where r is the radius.

So that:

r =

 = = 30 feet

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

                                           = 2 x x 30

                                           =

                                           = 188.57

                                           ≅ 189 feet

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

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
