A cylindrical swimming pool has a diameter of 16 feet and a height of 3 feet. How many gallons of water can the pool contain? Ro
Sever21 [200]

Answer:

<em>4,524 gallons</em>

Step-by-step explanation:

The volume of any cylinder is 

 π (radius)² (height) .

The pool's radius is 1/2 its diameter = 8 ft.  So its volume is

 π (8 ft)² (3 ft)

= π · (64 ft²) · (3 ft)

= π · 192 ft³

= 603.2 ft³ .

(603 ft³) · (7.5 gal / 1 ft³) = 4,524 gallons

Hope this helps :D

Expand and simply <br>a) 2(4c+5d)+3(c-3d) <br>b) 6(3m+n)-4(m-n)<br>​
dezoksy [38]

Answer:

a. 11x + d

b. 15m + 10n

Step-by-step explanation:

a. 2(4c+5d) + 3(x-3d)

Break the brackets:

2*4c + 2*5d + 3*x - 3*3d

= 8x + 10d + 3x - 9d

Collect like termsL

= 8x + 3x + 10d - 9d

= 11x + 1d

b. 6(3m+n) - 4(m-n)

Break the brackets:

= 6*3m + 6*n - 3*m - 4*(-n)

= 18m + 6n - 3m - (-4n)

= 18m -3m + 6n + 4n

= 15m + 10n

Hope this helped :3

PQRS is a square. find the value of x and y.
Ivan

Answer:

x = 7

y = 3/2 or 1.5 (IF THE ANGLE IS 30 BY THE RATIOS OF A RIGHT TRIANGLE.)

hope it's right

Step-by-step explanation:

FOR X:

Let's solve your equation step-by-step.

4x+3=31

Step 1: Subtract 3 from both sides.

4x+3−3=31−3

4x=28

Step 2: Divide both sides by 4.

4x/4=28/4

x=7

FOR Y:

Step 1: Simplify both sides of the equation.

(3)(7)+6y=30

21+6y=30

6y+21=30

Step 2: Subtract 21 from both sides.

6y+21−21=30−21

6y=9

Step 3: Divide both sides by 6.

6y/6=9/6

y=3/2
