Step-by-step explanation:

Given

Delivery amount = $120

Percent tip on the delivery amount = 15%

Tip amount = 15% * 120

How do you solve this problem?

The arcs $AB, BC, AC$ all equal to the third of the perimeter since equilateral triangle divides them like this.

So we need to find a perimeter but we are only given the area.

Let's review,

$A=\pi r^2 \\P=2\pi r$

That means that from area we area able to calculate radius.

$A=\pi r^2\Longrightarrow r=\sqrt{\dfrac{A}{\pi}}$

Insert the numbers,

$r=\sqrt{\dfrac{36\pi}{\pi}}=6$

Then use the perimeter formula to calculate perimeter since radius is known,

$P=2\pi\cdot6=12\pi$

Now divide perimeter by 3 to get length of AB arc.

$AB=\dfrac{12\pi}{3}=\boxed{4\pi}$

Hope this helps.

AURORKA [14]

Answer:

\large \boxed{\text{2.00 in}}

Step-by-step explanation:

The formula for the volume of a rectangular solid is

V = lwh

$\begin{array}{rcl}V & = & lwh\\187 & = & 8.5 \times 11 \times h\\& = & 93.5h\\h & = &\dfrac{187}{93.5}\\\\& = & \textbf{2.00 in}\\\end{array}\\\text{The ream is $\large \boxed{\textbf{2.00 in}}$ thick.}$
