Polygon Y is a scaled copy of Polygon X using a scale factor of \dfrac13 3 1 ​ start fraction, 1, divided by, 3, end fraction. P
emmainna [20.7K]

Answer:

Polygon Y's area is one ninth (1/9) of Polygon X's area

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

In this problem

Let

z-----> the scale factor

a-----> Polygon Y's area

b----> Polygon X's area

z^{2}=\frac{a}{b}

we have

z=\frac{1}{3}

substitute

(\frac{1}{3})^{2}=\frac{a}{b}

\frac{1}{9}=\frac{a}{b}

a=\frac{1}{9}b

therefore

Polygon Y's area is one ninth (1/9) of Polygon X's area

PLEASE HELP!! NO LINKS!!
dlinn [17]

Answer:

42.1 cm

Step-by-step explanation:

θ = 265°

Radius (r) = 9.1 cm

Arc length of major arc GH = θ/360 × 2πr

Plug in the values into the equation

Length of arc GH = 265/360 × 2 × π × 9.1

= 42.0886149

= 42.1 cm (nearest tenth)
