Answer:
The old fish tank hold <u>18.84 cubic feet</u> of water.
Step-by-step explanation:
Given:
An old fish tank in the form of a circular cylinder and it is 2 feet in diameter and 6 feet tall.
Now, to find the cubic feet of water the fish tank hold.
Dimensions of old fish tank are:
<em>Diameter is 2 feet so. we find the radius first.</em>
Radius (
) = 
Height (
) = 
Now, to get the cubic feet off water the tank hold we put formula:
<u><em>(Taking the value of π as 3.14.)</em></u>

Therefore, the old fish tank hold 18.84 cubic feet of water.
Notice the picture below, see the length "l"?
well

solve for "w", to find the width,
what's the length? well, l = 11/4 w
D. there is no numbers to work with so you just have to use a variable
Let us start dividing 30 by small prime numbers in increasing order .
the smallest prime number we use is 2
Let's divide 30 by 2 quotient is 15
so we get : 30 = 2* 15
15 is not a prime number , it can be factorized further .
now we start dividing 15
2 can not divide 15 so we move to next prime number that is 3
can 3 divide 15? yes .
we get a quotient 5
so 30 is now : 2* 15 = 2* 3*5
now we have to work on 5 but 5 is a prime number so we stop here .
the prime factorization of 30 is : 2* 3* 5
Answer : 2 *3*5
Because the lines are parallel, 75 is equal to 11x-2
75=11x-2
77=11x
x=7
