Explanation:

4.

En geometría, una porción continua de un círculo entre dos puntos distinctos se llama arco.

Step1: Identificar radios

Los radios de los círculos son $RT = RW=6.5$ cm (círculo $R$) y $ST = SW = 8.25$ cm (círculo $S$).

Step2: Calcular perímetro

El perímetro $P$ del cuadrilátero $RTSW$ es $P=RT + TS+SW + WR$. Sustituyendo valores: $P = 6.5+8.25 + 8.25+6.5$.
$P=(6.5 + 6.5)+(8.25+8.25)=13 + 16.5=29.5$ cm.

Answer:

(2) an arc
