Quadrilateral WXYZ is dilated by a scale factor of į to form quadrilateral W'X'Y'Z'. What is the measure of side ZW? Z 28 Y" 42
Brrunno [24]

Answer:

See Explanation

Step-by-step explanation:

Given

<em>The given side lengths are not clear enough:</em>

<em>So, I will give a general explanation.</em>

<em />

From the question, we understand WXYZ is dilated to produce W'X'Y'Z

This implies that the sides of WYZY is multiplied by the scale factor (k) to give W'X'Y'Z'

i.e.

ZW *k =Z'W'

Divide both sides by k to get side length ZW

ZW = \frac{Z'W'}{k}

Assume that:

k = 4 and

Z'W' = 28

ZW = \frac{Z'W'}{k}

ZW = \frac{28}{4}

ZW = 7

<em>Apply these steps and you will get your answer</em>

Please help me with this question
sergejj [24]

Answer:

49π

Step-by-step explanation:

Circle area: πr^2

Since A to C is 14, and they're both in the center, A to B and B to C will both be 7 as a radius.

Since we know the radius, we can put it in the formula, πr^2.

We only need to solve for one circle, since both circles are the same. By solving the circle, we will put in 7 for the radius, giving us π7^2, which is 49π.
