Step-by-step explanation:
<u>Step 1: Define</u>
55 > -7y + 6
<u>Step 2: Solve for </u><em><u>y</u></em>
Here we see that any value <em>y</em> greater than -7 would work as a solution to the inequality.
127.17cm²
Area of a semicircle: πr² ÷ 2
d = 18
r = 18/2 = 9
Area of a semicircle: 9²π ÷ 2 = 127.17cm²
17.2 cm
x^2 = 4^2 - 2^2
x^2 = 16 - 4
x^2 = 12
x = √12
x = 2√3
