Answer:
24’429.02 m^3
Step-by-step explanation:
1) find the radius
radius = diameter/2 = 36 / 2 = 18 m
2) find the volume
V = 4/3 x radius^3 x pi = 4/3 x 18^3 x pi = 4/3 x 5832 x pi = 7776 x pi = 24’429.02 m^3
Answer:
G 15.99h > 188.55 + 9.75h
Step-by-step explanation:
The ice cube tray can make 200.96 cubic centimeters of ice.
<h3>
How to get the total volume?</h3>
For a sphere of radius R, the volume is:
In this case, we have 6 spheres, each one with a radius of 2cm.
Then the total volume of ice that the ice cube tray can make at one time is:
The ice cube tray can make 200.96 cubic centimeters of ice.

Answer:
29.2
Step-by-step explanation:
Mean = 21.4
Standard deviation = 5.9%
The minimum score required for the scholarship which is the scores of the top 9% is calculated using the Z - Score Formula.
The Z- score formula is given as:
z = x - μ /σ
Z score ( z) is determined by checking the z score percentile of the normal distribution
In the question we are told that it is the students who scores are in the top 9%
The top 9% is determined by finding the z score of the 91st percentile on the normal distribution
z score of the 91st percentile = 1.341
Using the formula
z = x - μ /σ
Where
z = z score of the 91st percentile = 1.341
μ = mean = 21.4
σ = Standard deviation = 5.9
1.341= x - 21.4 / 5.9
Cross multiply
1.341 × 5.9 = x - 21.4
7.7526 = x -21.4
x = 7.7526 + 21.4
x = 29.1526
The 91st percentile is at the score of 29.1526.
We were asked in the question to round up to the nearest tenth.
Approximately, = 29.2
The minimum score required for the scholarship to the nearest tenth is 29.2 .
75% is the answer because you add 51 and 17 which is 68 then divide 51 by 68 which is 0.75 then times that by 100 it gives you 75
