Answer:
Step-by-step explanation:
volume of cylinder = πr²h
πr²h = 127.23 cubic inches
3.14 * 3 * 3 * h = 127.23
h = 127.23 / 3*3*3.14
=127.23 * 100 /3*3*3.14*100
=12723/ 3*3*314
= 4241 / 3*314
=4241/ 942
=4.502 inches
h = 4.5 inches
The area of a circle is represented by the equation:
We know that the diameter is two times the radius: 
So if we know that the diameter of the circle is 24m, we can divide this by two in order to get the radius:
-->
So then we can plug this radius in to the equation for the area of a circle:
We are told to use 3.14 as pi, and not pi itself, so let's plug in 3.14 for pi:
Now we know that the area of this circle is 452.16 square meters.
Step-by-step explanation:
The answer is the second choice. The outcome from rolling a fair die does not affect the outcome of drawing from a well-shuffled deck. The probability of rolling a 5 will always be 1/6, and the probability of drawing an Ace will always be 4/52.
On the other hand, the weather of a city can depend on the weather from the previous day.
Answer:
Adults =1500 and student= 2500
Step-by-step explanation:
Step one:
GIven data
let Adults be x and student be y in numbers
so
5x+3y=15000------------1
x+y=4000---------------------2
from 1
x=4000-y, put this in 2, we have
5(4000-y)+3y=15000
20000-5y+3y=15000
-2y=15000-20000
-2y= -5000
2y=5000
divide both sides by 2
y= 2500
put y= 2500 in 2
x+2500= 4000
x= 4000-2500
x=1500
