Dilation is a transformation of scaling that requires a center of scaling and a factor of scaling.
Similarity is a relationship between two figures when there is a special transformation that transforms one figure into another.
This transformation can include any combination of rotation, shift and dilation.
That's why a pair of a source and its image after dilation are similar, but not all similar figures can be connected by dilation. For instance, rotation and/or shift transform a figure into another, similar one to the original, but not related through dilation..

The area of a rectangle is 21 yd^2, and the length of the rectangle is 1 yd less than twice the width. Find the dimensions of th

inna [77]

Length = 6yd

width = 3.5yd

<u>Explanation:</u>

Let, width = b

So, length = 2b-1

area = 21yd

We know,

area of rectangle = length X width

So,

$21yd^{2} = (2b-1) X b$

$2b^{2} - b - 21 = 0$

On solving the above equation, we get

Width, b = 3.5yd

length, l = 6yd

The area of a rectangle is 0.8 square units. The length is 3.2 units and the width is x units. What is the value of x?

zhannawk [14.2K]

Answer: A. x= 0.25

Step-by-step explanation:

To find the area of a rectangle ,we need to multiply the length by the width.

It says the length is 3.2 and with is x so 3.2 times x has to equal 0.8 which is the area.

3.2 * x = 0.8 Now solve for x.

3.2x = 0.8 Divide both sides by 3.2

x= 0.25

A basketball team wants to paint half of a free-throw circle grey. If the radius of the free-throw circle is 5.4 feet, what is t

FromTheMoon [43]

Answer:

The area which would be painted grey will be "47.7812 ft²".

Step-by-step explanation:

The given values are:

Radius of circle, r = 5.4 feet

Value of pi, π = 3.14

As we know,

Area of Semicircle = $\frac{\pi r^2}{2}$

On putting the values in the above formula, we get

= $\frac{3.14\times (5.4)^{2}}{2}$

= $\frac{3.14\times 29.26}{2}$

= $\frac{91.5624}{2}$

= $45.7812 \ ft^2$
