Need help ASAP Thankyou
sineoko [7]

Answer:

Volume of the tank = 636 ft³

Step-by-step explanation:

Formula for the volume of a cylinder is,

V = πr²h

Where r = radius of the cylinder

h = height of the cylinder

By substituting the values of radius and height of the water tank given in the question,

V = \pi (4.5)^{2}(10)

   = 202.5π

   = 202.5 × (3.14)

   = 635.85 ft³

   ≈ 636 ft³

Therefore, volume of the cylindrical water tank is 636 ft³.

1. True or false:
Nitella [24]

1) true

2)false

Step-by-step explanation:

1) 5(3)+2(4) = 23

= 15+8=23

23=23

thus, (3,4) is solution for 5x + 2y = 23

2) 5(0)+2(4) =23

= 0+8 is not 23

thus, (0,4) is not solution for 5x + 2y = 23

For what values of x and y must each figure be a parallelogram?
daser333 [38]

9514 1404 393

Answer:

  x = 2

  y = 9

Step-by-step explanation:

Opposite sides of a parallelogram are the same length. This relation is used to make equations with the given side lengths.

<u>Top and Bottom</u>

  4x +20 = x +26

  3x = 6 . . . . . . . . . . . subtract x+20 from both sides

  x = 2 . . . . . . . . . divide by 3

<u>Left and Right</u>

 7y = 6y + 9

  y = 9 . . . . . . . . . subtract 6y from both sides
