Question

the field inside a running track is made up of a rectangle that is 84.39 m long and 73 m wide, together with a semicircle at each end. what is the distance around the inside of the track?

the two semicircles pushed together create a circle. the diameter of the circle is the width of the field. the circumference of the circle is the perimeter of the two ends.

\\(c = \pi d\\)

write your answer using \pi\ with no spaces.

\\(c =\\) m

use 3.14 for \\(\pi\\) to find the approximate circumference.

\\(c \approx\\) m

Explanation:

Identify the diameter of the circle

$$ d = 73\text{ m} $$

Calculate the exact circumference using "pi"

$$ C = 73\pi\text{ m} $$

Calculate the approximate circumference using 3.14

$$ C \approx 73 \times 3.14 = 229.22\text{ m} $$

Answer:

Question 1

Write your answer using "pi" with no spaces.
\(C =\) <blank>73pi</blank> m

Question 2

Use 3.14 for \(\pi\) to find the approximate circumference.
\(C \approx\) <blank>229.22</blank> m
