Answer:

  9π ≈ 28.3 square meters

Step-by-step explanation:

Using the given formula for the area of the circle, we find its area to be ...

  A = πr^2

  A = π(3 m)^2 = 9π m^2 ≈ 28.3 m^2

The height of a rectangular prism is 3 feet. The length and width can be expressed as x-1 and x+4. If the volume of the prism is
SashulF [63]

Answer:

Step-by-step explanation:

Volume  = 198 ft

length * width * height = 198

(x - 1) * (x + 4) * 3 = 198

(x - 1) * (x + 4)  = 198/3

(x - 1) * (x + 4) = 66

x*x + x*4 -1*x - 1*4 = 66   {Use FOIL method to multiply}

x² + 4x - x - 4 = 66

x² + 3x - 4 =66

x² + 3x - 4 - 66 = 0

x² + 3x - 70 = 0

Now factorize.

x² + 10x - 7x - 7*10 = 0

x(x +10) - 7(x + 10 ) = 0

(x + 10)(x - 7) = 0

x - 7 = 0 {x + 10 is ignored because measurement cannot be in negative}

x = 7

length = x - 1 = 7 - 1 = 6ft

Width = x + 4 = 7 + 4 = 11 ft

A parallelogram has verticies of (0,0) (0,6) (4,4) (4, -2). Which transformation maps the parallelogram onto itself?
gulaghasi [49]

The transformation that would map the parallelogram onto itself is the rotation of 180 degrees about the point (2, 2)

<h3>What is a transformation?</h3>

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.

Rigid transformation is the transformation that does not change the shape or size of a figure. Examples of rigid transformations are <em>translation, reflection and rotation</em>.

The transformation that would map the parallelogram onto itself is the rotation of 180 degrees about the point (2, 2)
