Answer:
h ~ 4.974
Step-by-step explanation:
The formula for the volume of a cylinder is;
Where represents the value,
represents the radius of the given cylinder. In other words, if one were to take a base (the flat side in the case of the cylinder) of the figure. The distance from the center to a point on the outside of the circle is the radius.
represents the height of the object. In other words the distance between the two bases of the cylinder.
represents the volume, in other words, the space that the object takes up.
In this problem, one is given the diameter of the cylinder and the volume. One is asked to find the area.
The diameter of a circle is the distance between two opposite sides of the circle. The diameter will always pass through the center of the circle. To find the radius when given the diameter, one will divide by 2.
To solve this problem, one will substitute in the given information and solve for the height using inverse operations.
Complete Question
En una piscina con forma rectangular mide 10 metros de largo y 4 metros de
ancho y se sabe que para llenar la piscina se necesitan 100 000 litros de agua.
a) ¿Cuál es el volumen de la piscina?
b) ¿Cuál es la profundidad de la piscina?
Answer:
a) ¿Cuál es el volumen de la piscina?
= 100 m³
b) ¿Cuál es la profundidad de la piscina?
= 2.5m
Step-by-step explanation:
a) Se nos da la cantidad de litros de agua necesarios para llenar la piscina = 100000 litros
Conversión a cm³
1 litro = 0.001 m³
100000 litros = x
x = 100000 × 0.001 m³
x = 100 m³
b) La profundidad de la piscina se calcula como:
Volumen de la piscina ÷ (Largo × Alto)
Longitud = 10 m
Altura = 4 m
Por eso,
100 m³ ÷ (10 m × 4 m)
100 m³ ÷ 40 m²
= 2.5 m
