The image is missing so i have attached it.
Answer:
Volume = 1.5 litres
Step-by-step explanation:
Using pythagoras theorem, we can get the height (h) of the cylinder
14² + h² = 17²
h² = 289 - 196
h = √93
Now, volume of a cylinder is;
V = πr²h
In the image, r = diameter/2 = 14/2 = 7cm
Thus,
V = π × 7² × √93
V = 1485 cm³
Now, 1 litre = 1000 cm³
Thus, volume = 1485/1000 = 1.485 litres ≈ 1.5 litres
Answer:
The water level change the most in week 3 and week 4
The change = -370 inches
Step-by-step explanation:
Given - Week 1 2 3 4 5
Water Level (inches) − 1 1 4 1 3 8 2 1 2 -1 5 8 -1 3 4
To find - Between which two weeks did the water level change the most? Calculate the change .
Proof -
The formula for change in water level with respect to week be-
Rate of Change in Water Level = Difference in water level / Difference in weeks
Now,
For week 1 and week 2
Rate of change in water level = =
= 24 inches
Now,
For week 1 and week 3
Rate of change in water level = =
= 49 inches
Now,
For week 1 and week 4
Rate of change in water level = =
= -90.67 inches
Now,
For week 1 and week 5
Rate of change in water level = =
= -62 inches
Now,
For week 2 and week 3
Rate of change in water level = =
= 74 inches
Now,
For week 2 and week 4
Rate of change in water level = =
= -148 inches
Now,
For week 2 and week 5
Rate of change in water level = =
= -90.67 inches
Now,
For week 3 and week 4
Rate of change in water level = =
= -370 inches
Now,
For week 3 and week 5
Rate of change in water level = =
= 173 inches
Now,
For week 4 and week 5
Rate of change in water level = =
= 24 inches
∴ we get
The water level change the most in week 3 and week 4
The change = -370 inches
Note :
The highest change means which temperature goes the most change in water level. It can be negative also.
So, We have to take the modulus and then find the highest number.
Here, 370 > 173
So, Highest change occurs in Week 3 and Week 4 but not in Week 3 and Week 5.
