Answer with explanation:

Quadrilateral has four sides.The Different types of Quadrilateral are:

1. Parallelogram----Opposite sides are Parallel.

2. Rhombus--Opposite sides are Parallel.

3. Square----Opposite sides are Parallel and adjacent sides are perpendicular.

4.Rectangle----Opposite sides are Parallel and adjacent sides are perpendicular.

5.Kite...............................

So, Slope formula is used to determine

Quadrilateral has either parallel or perpendicular sides.

Is it possible to find a value of $x$ so that the value of the surface area (in square inches) is equal to the value of the volu

Annette [7]

The box has volume

11 in × 3 in × x in = 33x in³

and surface area

2 (11 in × 3 in + 11 in × x in + 3 in × x in) = (66 + 28x) in²

The volume and area have the same value if

33x = 66 + 28x

Solve this equation for x :

33x - 28x = 66

5x = 66

x = 66/5 = 13.2

The diameter of this beach ball is 12 inches.

Wittaler [7]

Answer:

288π or 904.78

Step-by-step explanation:

We know that the diameter of this beach ball is 12 inches and we want to determine how much air it can hold using the formula for the volume of a sphere which is $\frac{4}{3}$ × π × r³ where 'r' is the radius. In the question we are given the diameter not the radius but we can half the diameter to find the radius so 12 ÷ 2 = 6. The radius of the beach ball is 6 inches so let's work out how much air it can hold.
