find the area of the semicircle. either enter an exact answer in terms of π or use 3.14 for π and enter your answer as a decimal. units²

Answer

Explanation:

Step1: Escribir la fórmula del área de un círculo

$A_{círculo}=\pi r^{2}$

Step2: Encontrar el área del semicírculo

$A_{semicírculo}=\frac{1}{2}\pi r^{2}$ Dado que $r = 10$, entonces $A_{semicírculo}=\frac{1}{2}\pi(10)^{2}$

Step3: Calcular el valor

$A_{semicírculo}=\frac{1}{2}\pi\times100 = 50\pi$ Si usamos $\pi = 3.14$, entonces $A_{semicírculo}=50\times3.14=157$

Answer:

$50\pi$ (respuesta exacta) o $157$ (respuesta decimal)
