Mathematics: 4. Kennedy and Tess are constructing a racetrack for their horses. The track encloses a field that is rectangular, with two semicircles at each end. A fence must surround this field. How much fencing will Kennedy and Tess need? Use the PI button NOT 3.14. Round to the nearest tenth. Label your answer for example meters . 1408 m 302 m

$3764.8 \:meters$ (to the nearest tenth)$

Step-by-step explanation:

The Length of fence needed will be the sum of the Length of the two rectangles and the two semicircles.

Perimeter of a Semicircle = $\pi r$

Perimeter of Two Semicircles $=2\pi r$

Radius of the Semicircle =302 ÷ 2 =151 m

Therefore:

Perimeter of the Two Semicircles at each end

$=2\pi *151\\=302\pi \:meters$

Length of the Two rectangular sides =1408+1408 =2816m

Therefore, Length of Fencing Needed

$=302\pi +2816\\=3764.76 \\\approx 3764.8 \:meters$ (to the nearest tenth)$
