Area = πr² ⇒
81π = πr² ⇒ 81 = r² ⇒ r = √81 = 9 in
<span>Circumference = 2</span>πr = 2*9*π = 18π in
Answer:
15 ≤ x - 10
Well, that's how you describe it, and I write it for you.
Use the slope-intercept form to find the slope and y-intercept.
Slope: 22
Y-Intercept: 3
To find the inverse, interchange the variables and solve for y.
f−1(x)=−3/2+x/2
Answer: $25.65
explanation: 14% of $22.50 is 3.15
22.50 + 3.15 = $25.65
hope this helps :)
