Find and compare the unit rates of decline:

Run "a":

-60 yds

------------- = -0.171 yds per yd

350 yds

Run b

115 yds

------------- = -0.290 yds per yd

550 yds

Slope (b) is the steeper.

Answer:

Swimming one time around the pool is 56.5 ft

Step-by-step explanation:

Swimming 18 ft from one side of her circular pool to the other, swimming straight through the center means the circular swimming pool has a diameter of d=18 ft.

The circumference of the circle is calculated using:

$c = \pi \: d$

where d=18 is the diameter and π=3.14 as given.

We substitute the values to get:

$c = 3.14 \times 18$

$c = 56.52$

We approximate to the nearest tenth to get:

$c = 56.5ft$
