Question

the diameter, d, of a sphere is 15.2 mm. calculate the spheres volume, v. use the value 3.14 for π, and round your answer to the nearest tenth. (do not round any intermediate computations.)

Explanation:

Step1: Encontrar el radio

El radio \( r \) es la mitad del diámetro \( D \). Entonces, \( r = \frac{D}{2} = \frac{15.2}{2} = 7.6 \) mm.

Step2: Fórmula del volumen de la esfera

La fórmula del volumen \( V \) de una esfera es \( V = \frac{4}{3}\pi r^3 \). Sustituimos \( \pi = 3.14 \) y \( r = 7.6 \).

Step3: Calcular \( r^3 \)

\( r^3 = 7.6^3 = 7.6 \times 7.6 \times 7.6 = 438.976 \).

Step4: Sustituir en la fórmula

\( V = \frac{4}{3} \times 3.14 \times 438.976 \). Primero, calculamos \( \frac{4}{3} \times 3.14 \approx 4.1867 \). Luego, \( 4.1867 \times 438.976 \approx 1837.8 \) (redondeando al décimo).

Answer:

1837.8
