Answer:
Step-by-step explanation:
Let the number be x
<u>Then we have the equation</u>
- (2x + 6)*(-3) = -3x + 54
- -6x - 18 = -3x + 54
- 6x - 3x = -18 - 54
- 3x = -72
- x = -72/3
- x = - 24
<h2><u>S</u><u>o</u><u>l</u><u>u</u><u>t</u><u>i</u><u>o</u><u>n</u><u> </u></h2>
let the number be "x" .
now according to the given question ;
- (2x+6)×(-3)=-3x +54
- -6x -18 = -3x + 54
- 6x - 3x = -18-54
- 3x = -72
- x = -72/3
- x = -24

The required answer is -24 .</h2>

Step-by-step explanation:
Area of circle = π r²
r = 30
30² = 900
π = 3.14 or ≈ 3
A ≈ 900 × 3
A ≈ 2700
so C at 2830 is closest to the answer
