A) See the attached graph. The purple area appears to be what you want to find.
b) Integrating with respect to x seems much easier. If one were to integrate over y, there would need to be two regions of integration: [1, e^2] and [e^2, e^4].
c)
Answer:
AC = 6√3 in
Step-by-step explanation:
<h3>Finding the length of the chord:</h3>
Join OC. Now ΔAOC is an isosceles triangle as OA = OC =radius.
∠A = ∠C = 30.
∠A + ∠C + ∠AOC = 180 {angle sum property of traingle}
30 + 30 + ∠AOC = 180°
∠AOC = 180 -60
∠AOC = Ф = 120°
Find the length of radius using the bellow formula.

Ф = 120°
Arc length = 4π




2c-9=c
-9=-c
9=c
Hope that helps!
I'm going to use numbers but is the same thing example:Aa
