It is given in the question that the formula of volume of cone is

Where V is the volume, r is the radius and h is the height.
And we have to find an expression for h.
First we multiply both sides by 3, and on doing that we will get

Now to isolate h, we have to get rid of pi r square by dividing.

Therefore the correct option is B.
Division is multiplication by a fraction
54/3=(3*18)/3=18
105/7=(7*15)/7=15

The normal distribution is also known as the Gaussian distribution. The correct option is D, while the z-score is -2.29.
<h3>What is Normal Distribution?</h3>
The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data distant from the mean. The normal distribution will show as a bell curve on a graph.
Since the normal distribution is symmetrical about the mean. Therefore, 0.89 area from the left will be equal to 0.11 area from the right. Therefore, the correct option is D, while the z-score is -2.29.
