Question
the diameter, d, of a sphere is 14.8 m. calculate the sphere’s 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, \( r = \frac{D}{2} = \frac{14.8}{2} = 7.4 \, \text{m} \).
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 \( r = 7.4 \):
Primero, calculamos \( (7.4)^3 = 7.4 \times 7.4 \times 7.4 = 405.224 \).
Luego, \( \frac{4}{3} \times 3.14 = \frac{12.56}{3} \approx 4.1867 \).
Multiplicamos por \( 405.224 \): \( 4.1867 \times 405.224 \approx 1703.9 \) (redondeando al décimo).
