Answer:
SA =64 pi units ^2
Step-by-step explanation:
The surface area of a sphere is given by
SA = 4 pi r^2
SA = 4 * pi * 4^2
SA =64 pi
SA =200.96
So we will be using dimensional analysis to solve it as such:
![\frac{23843\ kL}{1}*\frac{1000\ L}{1\ kL}*\frac{1\ Gal}{3.79\ L}=\frac{23843000}{3.79}=6291029.02\ Gallons](https://tex.z-dn.net/?f=%20%5Cfrac%7B23843%5C%20kL%7D%7B1%7D%2A%5Cfrac%7B1000%5C%20L%7D%7B1%5C%20kL%7D%2A%5Cfrac%7B1%5C%20Gal%7D%7B3.79%5C%20L%7D%3D%5Cfrac%7B23843000%7D%7B3.79%7D%3D6291029.02%5C%20Gallons%20)
In short, 23,843 kL is 6,291,029.02 (6,291,029 rounded to the whole gallon) gallons.
The relative frequency of selecting a diamond from 40 trials of selecting a random card is 30%.
<h3>What is relative frequency?</h3>
The relative frequency of an event is the ratio of total number of favorable or desired outcome to the total number of trails done.
Given information-
The card is selected random from the deck of cards.
Total number of trails is 40.
It is known that the total number of diamond card in a standard deck of card is 11. There is total 40 trials is done in which a random card is selected.
As the relative frequency is the ratio of total number of diamonds to the total number of trials done. Thus,
![f_r=\dfrac{11}{40}\\f_r=0.3](https://tex.z-dn.net/?f=f_r%3D%5Cdfrac%7B11%7D%7B40%7D%5C%5Cf_r%3D0.3)
In the percentage from,
![f_r={0.3}\times100\\f_r=30](https://tex.z-dn.net/?f=f_r%3D%7B0.3%7D%5Ctimes100%5C%5Cf_r%3D30)
Thus the relative frequency of selecting a diamond from 40 trials of selecting a random card is 30%.
