I do need help with this problem that includes pi. ^_^

Troyanec [42]

Solution:

Note that:

Circumference = 50.24 ft = 2πr = πd
Dia. = 16 ft.

Divide the diameter both sides.

50.24 ft = πd
=> 50.24/d ft = πd/d
=> 50.24/d ft = π

Substitute the diameter in the equation.

=> 50.24/16 = π (Option A)

Answer:

$x=-1\text{ or }x=11$

Step-by-step explanation:

For $a=|b|$ , we have two cases:

$\begin{cases}a=b,\\a=-b\end{cases}$

Therefore, for $18=|15-3x|$ , we have the following cases:

$\begin{cases}18=15-3x,\\18=-(15-3x)\end{cases}$

Solving, we have:

$\begin{cases}18=15-3x, -3x=3, x=\boxed{-1},\\18=-(15-3x), 18=-15+3x, 33=3x, x=\boxed{11}\end{cases}$ .

Therefore,

$\implies \boxed{x=-1\text{ or }x=11}$
