In triangle WXV and SRT,

If both triangles are similar than their ratio of corresponding sides are equal.

⟹\frac{XY}{XW} = \frac{US}{SR}

⟹\frac{27}{3x-21} = \frac{24}{x+13}

⟹(27)(x+13) = (24) (3x-21)

⟹27x +351 = 72x - 504

⟹27(x+13) = 9(8x-56)

⟹3x+39 = 8x-56

⟹8x-3x = 39+56

⟹5x = 95

<h2>⟹x=19</h2>

In triangle DFE and IHJ,

If both triangles are similar than their ratio of corresponding sides are equal.

⟹\frac{GF}{EF} = \frac{IK}{HI}

⟹\frac{9}{x+8} = \frac{14}{3x-2}

⟹(9)(3x-2) = (14)(x+8)

⟹27x-18=14x+112

⟹27x-14x=112+18

⟹13x=130

⟹x =\frac{130}{13}

<h2>⟹x=10</h2>

⟹EF = x+8

⟹EF =10+8

<h3>⟹EF=18</h3>

Please help me... Question is in the picture
Butoxors [25]
Ok so as it says, the equation for the circumference (C) is C=2(pi)r.
Pi is about 3.14, so all you have to do is multiply those three values together for the circumference.
C=2•3.14•4
C= 25.12

So the answer would be D, 25.12.
