Volume of a cylinder = area of base x height:
50.24 x 3 = 150.72 ft^3
Just add the numbers if the letters are the same only I multiplying do you add the exponents
Answer 14 b^5
The probability that the first slice of the cake will have the marble exists
7/66.
<h3>How to determine the probability using parts A and B?</h3>
Part A of the question demands that the volume of the cake be
estimated.
The volume of the cake exists, 


The part B of the question requires that the volume of each cut be
computed
The volume of each cut exists, V = 27
To estimate the required probability
We simply divide the volume of each cut by the volume of the cake.


Expand 


Therefore, the probability that the first slice of the cake will contain the
marble exists at 7/66.

The equation can be used to find the missing leg in the triangle
.
<h3>What is the right triangle?</h3>
A right-angle triangle is a triangle that has a side opposite to the right angle the largest side and is referred to as the hypotenuse.
It is given that a right triangle has a side length of 16 meters and a hypotenuse of 20 meters.
From a Pythagoras theorem

Thus, the equation can be used to find the missing leg in the triangle

The length of both AB and DC is the same.
19 degrees
We want to know the arc measure for the whole circle, except for DC. So, we can subtract the arc measure of DC from 360 to find DBC. Since we found DC above, all we need to do is subtract.
360 - 19 = 341
DBC = 341 degrees
Hope this helps!! :)
