Answer:
Solve for K by simplifying both sides of the inequality, then isolating the variable.
Inequality Form:
k > 1
<u>Interval Notation</u>:
(1, ∞)
Step-by-step explanation:
Area = πr² ⇒
81π = πr² ⇒ 81 = r² ⇒ r = √81 = 9 in
<span>Circumference = 2</span>πr = 2*9*π = 18π in
No because if you plug in 4 for x and 5 for y you get -4 not 36
