Savatey [412]

Probability of randomly rolling a 3 is 1/4

Step-by-step explanation:

Step 1:

It is given that a tetrahedron has 4 sides with 1,2,3 and 4 and is randomly rolled. We need to compute the probability of randomly rolling a 3.

Step 2:

Probability of an event = (Favorable outcomes) / (Total outcomes).

There are 4 total outcomes when the tetrahedron is rolled, these are the values 1 to 4.

The only favorable outcome is getting a 3

Probability of getting a 3 when the tetrahedron is randomly rolled = 1/4

Step 3:

A circular opening of an ice cream cone has a diameter of 23 centimeters. The height of the cone is 17 centimeters, what is the

Ahat [919]

Answer: $2355.31\ cm^3$

Step-by-step explanation:

Given

diameter of the cone is $d=23\ cm\quad [r=\frac{d}{2}=11.5\ cm]$

The height of the cone is $h=17\ cm$

The volume of a cone is $V=\dfrac{1}{3}\pi r^2h$

Insert the values

$\Rightarrow V=\dfrac{1}{3}\times \dfrac{22}{7}\times 11.5^2\times 17=2355.309\\\\\Rightarrow V\approx 2355.31\ cm^3$

Thus, the volume of the cone is $2355.31\ cm^3$
