Calculating the Volume of a Hemisphere
<p>Para encontrar el volumen de un hemisferio, primero calculamos el volumen de una esfera completa y luego dividimos el resultado por dos, ya que un hemisferio es la mitad de una esfera.</p> <p>El volumen \( V \) de una esfera se calcula con la fórmula:</p> \[ V = \frac{4}{3}\pi r^3 \] <p>Donde \( r \) es el radio de la esfera. En este caso, el diámetro de la esfera es de 8 cm, por lo que el radio \( r \) es de 4 cm.</p> <p>Sustituimos el radio en la fórmula para obtener el volumen de una esfera completa:</p> \[ V_{esfera} = \frac{4}{3}\pi (4\text{ cm})^3 \] \[ V_{esfera} = \frac{4}{3}\pi \cdot 64\text{ cm}^3 \] \[ V_{esfera} = \frac{256}{3}\pi \text{ cm}^3 \] <p>Dividimos este volumen por dos para obtener el volumen del hemisferio:</p> \[ V_{hemisferio} = \frac{V_{esfera}}{2} \] \[ V_{hemisferio} = \frac{256\pi}{6}\text{ cm}^3 \] \[ V_{hemisferio} = \frac{128\pi}{3}\text{ cm}^3 \] <p>Por lo tanto, el volumen del hemisferio es \( \frac{128\pi}{3}\text{ cm}^3 \).</p>
Calculating the Circumference of a Circle Using a Given Diameter
<p>Given that the diameter $d = 2r$, and $ \pi = \frac{22}{7} $, we can find the circumference $C$ of a circle using the formula:</p> <p>$ C = \pi d $</p> <p>Substituting the given values:</p> <p>$ C = \frac{22}{7} \times d $</p> <p>Now, replace $d$ with the given diameter value to find the circumference.</p>
Geometric Problem with Circle and Points
The image depicts a geometric problem involving a circle with points labeled A, B, C, D, and E, and a central point O. Some parts of the figure are labeled, such as AE as the diameter and OC as a radius measuring 2.5 cm. To give you a precise answer, I need to know the specific question you are looking to solve for this diagram. Could you please provide the question associated with this geometric figure?
