Question

a company rents water tanks shaped like cylinders. each tank has a radius of 5 feet and a height of 3 feet. the cost is $3 per cubic foot. how much does it cost to rent one water tank? use 3.14 for π, and do not round your answer.

Explanation:

Step1: Calcular el volumen del cilindro

La fórmula del volumen de un cilindro es \( V = \pi r^2 h \). Dado \( r = 5 \) pies, \( h = 3 \) pies y \( \pi = 3.14 \), sustituimos:
\( V = 3.14 \times 5^2 \times 3 \)
\( 5^2 = 25 \), entonces \( V = 3.14 \times 25 \times 3 \)
\( 3.14 \times 25 = 78.5 \), luego \( 78.5 \times 3 = 235.5 \) pies cúbicos.

Step2: Calcular el costo de alquilar

El costo es \( \$3 \) por pie cúbico. Multiplicamos el volumen por el costo por pie cúbico:
\( \text{Costo} = 235.5 \times 3 \)
\( 235.5 \times 3 = 706.5 \)

Answer:

\( \$706.5 \)
