Step-by-step explanation:
Answer:
127.17cm²
Step-by-step explanation:
Area of a semicircle: πr² ÷ 2
d = 18
r = 18/2 = 9
Area of a semicircle: 9²π ÷ 2 = 127.17cm²
Answer:
x = 5 only
≡ On a graph, the point touches (5, 0), making <em>x</em> equal to 0.
≡ In other words, you must replace <em>y</em> with <em>0</em> to solve for <em>x. </em>There is no <em>y</em> term in this problem, so you must determine <em>y</em> by separating the coefficients into groups and determining each part.
The answer to this is 2000...
hope this helps and HAGD!
