Answer:
The cone'll require about 37.5 cm of tubing
Step-by-step explanation:
To do this, we need to know that the volume of the medium will have to be the same volume of the cone that will be printed.
Then, the volume of the cone is:
V = π*r^2*h/3
V = 3.14 * 5^2*8 / 3 = 209.33 cm^3
We can assume that the tubing is a cylinder so:
V = π*r^2*h
The radius is 1 1/3, and this is:
1*3 + 1 = 4/3
Solving for h we have:
h= V/π*r^2
h = 209.33 / 3.14*(4/3)^2
h = 209.33 / 5.58
h = 37.5 cm
The change in grandpa Ernie's height each year is equal to 0.6cm.
As given in the question,
Number of years for which grandpa's height is shrinking = 4 years
The total decrease in height after four years is equal to 2.4cm.
Let x represents the decrease in height each year
The required equation to calculate decrease in height each year is given by:
4x = 2.4
⇒ x= 2.4 /4
⇒x = 0.6cm
Therefore, the change in grandpa Ernie's height each year is equal to 0.6cm.
The complete question is :
Grandpa Ernie is shrinking over the past four years his height decreased by a total of 2.4 cm it decrease by the same amount each year what was the change in grandpa Ernie’s height each year.
