Dilatation is the transformation that produces and image that is the same shape as the original, but different size. So, in order to find the dilatation of a triangle, you need to multiplícate by a scale factor the given coordinates. An ex: A'(0,2), B'(2,-1), and C'(-2,-2) , lets say that you are going to múltiple by 2, the formula would be (2x, 2y), and the results will be A'(0,4) B'(4,-2), C' (-4,-4).

Solving for an Unknown Using the Distributive Property
ArbitrLikvidat [17]

<em><u>Complete Question:</u></em>

The equation a= 180(n-2)/n represents the angle measures, a, in a regular n-sided polygon. When the equation is solved for n, n is equal to a fraction with a denominator of a – 180. What is the numerator of the fraction?

<em><u>Answer:</u></em>

The numerator of fraction is -360

<em><u>Solution:</u></em>

Given that,

<em><u>The equation represents the angle measures, a, in a regular n-sided polygon is:</u></em>

a = \frac{180(n - 2)}{n}

We have to solve the equation for "n"

Rearrange the equation

a \times n = 180(n - 2)\\\\a \times n = 180n - 360\\\\an - 180 n = -360\\\\Take\ n\ as\ common\ factor\\\\n(a-180) = -360\\\\n = \frac{-360}{a - 180}

Thus the numerator of the fraction is -360

Answer:

we are going to use the formula...
V=πr2h

Step-by-step explanation:

so

V = (3.14) 4x4 (9)

V = (3.14) 16 x 9

V = 3.14 x 144

V = 452.16

Hence, the third or C
