A rectangular prism and a cylinder have the same height. The length of each side of the prism base is equal to the diameter of t

NARA [144]

Answer:

The rectangular prism has the greater volume

Step-by-step explanation:

Given

Prism:

$Length = Width = a$

$Height = h$

Cylinder

$Diameter = a$

$Height = h$

Required

Shape with greater volume

The volume of a rectangular prism is:

$Volume = Length * Base * Height$

So, we have:

$V_1 = a*a*h$

$V_1 = a^2h$

The volume of a cylinder is:

$Volume = \pi r^2h$

Where

$r = \frac{d}{2}$

$r = \frac{a}{2}$

So, we have:

$V_2 = \pi *(a/2)^2 h$

$V_2 = \pi *\frac{a^2}{4} h$

$\pi = 3.14$

So:

$V_2 = 3.14*\frac{a^2}{4} h$

$V_2 = \frac{3.14}{4} a^2h$

$V_2 = 0.785 a^2h$

So, we have:

$V_1 = a^2h$

$V_2 = 0.785 a^2h$

Both expressions have the same factor but different coefficient

The expression with greater coefficient has the greater volume

So, the $rectangular$ $prism \\$ has the $greater$ $volume$

Because: $1 > 0.785$

25% of the time there is free breakfast at work. You just woke up and are really hungry, so you call your coworker who is alread

Mice21 [21]

Answer:

0.17

Step-by-step explanation:

The number of times there is free Breakfast at work = 25%

The number of times the coworker lies = 1/3

The number of times the coworker speaks truth = 2/3

How likely is it that there is free breakfast at work today:

For this to happen both conditions must be satisfied. There must be free breakfast at work AND the coworker has also spoken truth. Now in this condition we will use the AND rule of Probability where we will take the Product of both the probabilities.

Result = 0.25 x 0.67 = 0.17
