what is the volume of this sphere? use $piapprox3.14$ and round your answer to the nearest hundredth. 20 m cubic meters

Answer

Explanation:

Step1: Identificar el radio

El diámetro es 20 m, entonces el radio $r = \frac{20}{2}=10$ m.

Step2: Aplicar la fórmula del volumen de una esfera

La fórmula del volumen $V$ de una esfera es $V=\frac{4}{3}\pi r^{3}$. Sustituyendo $r = 10$ m y $\pi\approx3.14$: $V=\frac{4}{3}\times3.14\times10^{3}$ $V=\frac{4}{3}\times3.14\times1000$ $V=\frac{12560}{3}\approx4186.67$ m³

Answer:

$4186.67$
