Question
the diameter, d, of a sphere is 7.6 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.)
Step1: Encontrar el radio
El radio \( r \) es la mitad del diámetro \( D \). Entonces, \( r = \frac{D}{2} \). Dado que \( D = 7.6 \, \text{mm} \), entonces \( r = \frac{7.6}{2} = 3.8 \, \text{mm} \).
Step2: Usar la fórmula del volumen de la esfera
La fórmula para el volumen \( V \) de una esfera es \( V = \frac{4}{3} \pi r^3 \). Sustituimos \( \pi = 3.14 \) y \( r = 3.8 \):
Primero, calculamos \( (3.8)^3 = 3.8 \times 3.8 \times 3.8 = 54.872 \).
Luego, \( \frac{4}{3} \times 3.14 = \frac{12.56}{3} \approx 4.1867 \).
Entonces, \( V \approx 4.1867 \times 54.872 \approx 229.8 \) (redondeando al décimo).
