The diameter of this beach ball is 12 inches. a beach ball. apply the formula for the volume of a sphere to determine how much a
1 answer:
The beach ball can hold 904.78 of air.
A sphere is a solid three dimensional shape with no edges or vertices.
Its diameter is same as the height of the sphere. examples of spherical shape is a ball.
Analysis:
The volume of a sphere is π
.
diameter = 12 inches, radius = 12/2 = 6inches
volume of air the beach ball can hold = x 3.14159 x
= 904.78
in conclusion, the volume of air the beach ball would hold is: 904.78

Answer:
1)
2) 12 inches tall.
Step-by-step explanation:
1) The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" is the y-intercept.
In this case:
(The height of the candle in inches)
(The time in hours)
Then, we can rewrite it:
Based on the information provided in the exercise, the line passes through these points:
and
Then, we can find the slope of the line with the formula :
Now we need to substitute the slope and one of the points into and then solve for "b":
Substituting values, we get that the a linear equation that models the relationship between the heigth of the candle and the time, is:
2) We must substitute into the linear equation
in order to find the height of the candle after burning 8 hours:
