Answer:
The range of given data set is 90.
Step-by-step explanation:
We are given the following data:
20.9, 33.1, 21.8, 58.5, 23.5, 110.9, 30.4, 24.9, 74.1, 60.3, 40.4, 45.4
When this data is arranged in ascending order, we get:
20.9 , 21.8 , 23.5 , 24.9 , 30.4 , 33.1 , 40.4 , 45.4 , 58.5 , 60.3 , 74.1 , 110.9
Range is a measure of dispersion and can be easily calculated.
Formula:
Thus, the range of given data set is 90.
Answer:
The volume of tank to the nearest cube is 503 ft³
Step-by-step explanation:
Given that,
Diameter of tank = 8 ft
radius = 4 ft
Height = 10 ft
We need to calculate the volume of tank
Using formula of volume
Where, r = radius
h = height
Put the value into the formula
Hence, The volume of tank to the nearest cube is 503 ft³
