= 48.43552415324934
Answer:
Step-by-step explanation:
The answer choices don’t make sense. The volume of a cylinder of height 45mm and radius 5mm = π5²*45 = 1125π mm³.
Three of the answer choices are larger than 1125π.
:::::
volume of one cone = πr²h* ⅓
Volume of cylinder section = πr²h
Total volume = πr²h*⅔ + πr²h = πr²h*5/3 = π5²*15*5/3 = 625π
Answer:
Part a)
Part b) 
Step-by-step explanation:
Let
x------> the time in minutes
y-----> the total numbers of words
step 1
we have
-----> given table
<u>Find the slope of the linear equation</u>

with the slope m and the point A find the equation of the line
The equation of the line in point slope form is equal to

substitute


----> This is a linear direct variation
Part b) For 
substitute the value of x in the linear equation to find the value of y
