what is the volume of this sphere? use π ≈ 3.14 and round your answer to the nearest hundredth. 8 cm cubic centimeters

Answer

Answer:

$2143.57$

Explanation:

Step1: Encontrar el radio

El diámetro es 8 cm, entonces el radio $r = \frac{8}{2}=4$ cm.

Step2: Aplicar la fórmula del volumen de una esfera

La fórmula del volumen de una esfera es $V=\frac{4}{3}\pi r^{3}$. Sustituyendo $r = 4$ cm y $\pi\approx3.14$, tenemos $V=\frac{4}{3}\times3.14\times4^{3}$.

Step3: Calcular el valor

$4^{3}=4\times4\times4 = 64$, entonces $V=\frac{4}{3}\times3.14\times64=\frac{4\times3.14\times64}{3}=\frac{803.84}{3}\approx2143.57$ $cm^{3}$.
