Answer:

As this value is definite (has an end), it would be considered rational.
1). Recall the formula for the volume of a cylinder:
Volume = (pi) x (radius of the round end)² x (length or height) .
2). Gather together the number you'll use for pi, the radius of the
cylinder's round end, and its length or height. Make sure that the
radius of the round end and the length or height are in the same units.
If they're not, then convert something so that they are.
3). Write each number into its place in the formula.
4). Perform the indicated operations. The final number is the
volume of your cylinder.
Answer:
(500÷1.8)÷60
By dividing 1.8 out of 500, u can know
Answer:
There is a linear correlation between the chest size and weight
Proportion of the variation in weight can be explained by the linear relationship between weight and chest size is 0.006724 .
Step-by-step explanation:
Null Hypothesis:
= There is no linear correlation between the chest size and weight
Alternative Hypothesis :
=There is a linear correlation between the chest size and weight
The value of the linear correlation coefficient is r=0.882.
n = 8
Formula : 


Degree of freedom = n-1 = 8-1 = 7
α =0.05
so, p value is 2.365
t calculated > t critical
So, we reject the null hypothesis
So, There is a linear correlation between the chest size and weight
The proportion of the variation in weight can be explained by the linear relationship between weight and chest size = 
Hence proportion of the variation in weight can be explained by the linear relationship between weight and chest size is 0.006724 and There is a linear correlation between the chest size and weight
