Question

un campo de entrenamiento se forma uniéndo un rectángulo a dos semicírculos, tal y como se muestra. ¿cuál es la longitud de la pista que rodea al campo? (utilizar el valor 3.14 para π, y no redondear la respuesta.) 62 m 93 m

Explanation:

Step1: Calculate the circumference of the circle

The two semi - circles together form a complete circle. The diameter of the circle is $d = 62$ m. The formula for the circumference of a circle is $C=\pi d$. Substituting $\pi = 3.14$ and $d = 62$ m, we get $C = 3.14\times62= 194.68$ m.

Step2: Add the lengths of the two straight - parts

The length of each straight - part of the track is 93 m, and there are 2 straight - parts. The total length of the straight - parts is $2\times93=186$ m.

Step3: Calculate the total length of the track

The total length of the track is the sum of the circumference of the circle and the total length of the straight - parts. So, $L=194.68 + 186=380.68$ m.

Answer:

$380.68$ m
