Question
un campo de entrenamiento se formó al unir un rectángulo con dos semicírculos, como se ve a continuación. el rectángulo mide 86 m de largo y 60 m de ancho. hallar el área del campo de entrenamiento. utilizar el valor 3.14 para π, sin redondear la respuesta. incluir las unidades correctas en la respuesta.
Step1: Calculate the area of the rectangle
The formula for the area of a rectangle is \(A_{rectangle}=length\times width\). Given \(length = 86m\) and \(width=60m\), then \(A_{rectangle}=86\times60 = 5160m^{2}\).
Step2: Calculate the area of the two - semicircles (equivalent to one full circle)
The formula for the area of a circle is \(A_{circle}=\pi r^{2}\). The diameter \(d = 60m\), so the radius \(r=\frac{d}{2}=\frac{60}{2}=30m\). Using \(\pi = 3.14\), then \(A_{circle}=3.14\times30^{2}=3.14\times900 = 2826m^{2}\).
Step3: Calculate the total area of the training field
The total area \(A = A_{rectangle}+A_{circle}\). So \(A=5160 + 2826=7986m^{2}\).
