Answer:

30.285 m²

Step-by-step explanation:

C = 2πr

2 · π · 2

≈ 12.57

12.57 ÷ 2 = 6.285

10 - 2 = 8

8 · 4 ÷ 2

32 ÷ 2

2 · 4 = 8

6.285 + 8 + 16

30.285

Here this is the new one.

Helga [31]

Formula #1: 0.15x + 22

Formula #2: 0.19x

0.15x + 22 = 0.19x

$15x+2200=19x\\15x=19x-2200\\-4x=-2200\\\frac{-4x}{-4}=\frac{-2200}{-4}\\X = 550$

So x = 550.

I hope this helps! :)
