Question

a dartboard consists of a circle inscribed in a square. the area of the circle is 16π square inches. the area of the square is 64 square inches. izzy randomly throws a dart at the square, and it lands inside the square. to the nearest percent, what is the probability that the dart lands inside the square but not on the circular dartboard? use 3.14 for π. 22% 25% 75% 79%

Explanation:

Step1: Encontrar el área no - circular

El área del cuadrado es $A_{cuadrado}=64$ pulgadas cuadradas y el área del círculo es $A_{circulo}=16\pi\approx16\times3.14 = 50.24$ pulgadas cuadradas. Entonces, el área no - circular $A = A_{cuadrado}-A_{circulo}=64 - 50.24=13.76$ pulgadas cuadradas.

Step2: Calcular la probabilidad

La probabilidad $P$ de que el dardo caiga en el área no - circular es $P=\frac{A}{A_{cuadrado}}\times100\%=\frac{13.76}{64}\times100\%$. $\frac{13.76}{64}=0.215$, y $0.215\times100\% = 21.5\%\approx22\%$.
