Answer:

El área del cuadrado es de 3 centímetros cuadrados.

Step-by-step explanation:

Dado que se desea pintar un cuadrado inscrito en una circunferencia de radio R=3cm como se muestra en la figura, para calcular el área del cuadrado se debe realizar el siguiente cálculo:

Radio = diámetro / 2

3 = X/2

X = 6

Hipotenusa del triángulo interno: 6 cm

Aplicando teorema pitagórico: lado al cuadrado mas lado al cuadrado es igual a hipotenusa al cuadrado.

L^2 + L^2 = 6

2L^2 = 6

L^2 = 6/2

L = √ 3

L = 1.732

Área de un cuadrado = L x L = L^2 = 3

Por lo tanto, el área del cuadrado es de 3 centímetros cuadrados.

Answer:

El área del cuadrado es de 18 centímetros cuadrados.  

Step-by-step explanation:

Dado que existe un cuadrado inscrito en un círculo, la medida de la <u>diagonal del cuadrado</u> es igual a la medida del <u>radio del círculo</u>. Además, conocemos que un cuadrado está formado por 4 triángulos rectángulos con configuración angular 45-45-90. Entonces, la medida del lado del cuadrado se calcula mediante la siguiente relación geométrica:

l = \sqrt{2}\cdot R (1)

Donde:

R - Radio del círculo, en centímetros.

l - Longitud del lado del cuadrado, en centímetros.

Por otra parte, la ecuación de área del cuadrado es igual a:

A = l^{2} (2)

Donde A es el área del cuadrado, en centímetros cuadrados.

Si sabemos que R = 3\,cm, entonces el área del cuadrado es:

l = \sqrt{2}\cdot (3\,cm)

l = 3\sqrt{2}\,cm

A = (3\sqrt{2}\,cm)^{2}

A = 18\,cm^{2}

El área del cuadrado es de 18 centímetros cuadrados.

Brut [27]

Answer: 13^0=1

Step-by-step explanation:

Logarithms are in the format log_{b} a=c while exponential form is in the format b^c=a

So we can transfer a,b, and c from the log form to the exponential form

log_{13} 1=0\\\\13^0=1

vredina [299]

Answer:

Current impact in pollution units per day=21.6 billion pollution units per day

Step-by-step explanation:

1 person consumes 3000 kilo-calories per person

Current population=7.2 billion people

Total calories the entire population produces=(7.2 billion×3000)

1000 kilo-calories causes= 1 pollution unit

To get the impact of the entire population=(7.2 billion×3000)/1000=21.6 billion pollution units per day
