The area of a circle = πR², where π=3.1459... & R = Radius

The area of our circle  ≈ 206 ft² = πR², Solve for R²:

R² =206/π ==>R² = 206/3.1459==> R² =65.5 ==> R=√65.5 ≈8 ft

Identify the solution to the following inequality: -1/2 (x+3) > x - 3
mrs_skeptik [129]

Answer:

A

Step-by-step explanation:

- \frac{1}{2} (x + 3) > x - 3 ( multiply both sides by 2 to clear the fraction )

- (x + 3) > 2x - 6 ← distribute parenthesis on left side by - 1

- x - 3 > 2x - 6 ( subtract 2x from both sides )

- 3x - 3 > - 6 ( add 3 to both sides )

- 3x > - 3

divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity

x < 1
