Answer :

  • 19.42 inches

⠀

Step-by-step explanation :

⠀

We know that,

{\longrightarrow \qquad \frak {\pmb{ 2 \pi r = Circumference_{(circle)} }}}

⠀

Here,

  • <em>r</em> is the radius of the circle.

  • We'll take the value of π as 3.14 .<em> (Answer may be different if we take the value of it as 22/7)</em>

⠀

Now, substituting the values :

⠀

{\longrightarrow \qquad \sf{ 2 \times 3.14 \times r = 122}}

⠀

{\longrightarrow \qquad \sf{ 6.28 \times r = 122}}

⠀

{\longrightarrow \qquad \sf{  r =  \dfrac{122}{6.28} }}

⠀

{\longrightarrow \qquad  \frak{\pmb{  r = 19.42}}}

⠀

Therefore,

  • The radius of the object is 19.40 inches approximately <em>(Rounded to nearest tenth) </em>

Answer:

given - circumference of the coin = 122 inches.

  • to calculate - radius of the coin.

______________________________________

\fbox\pink{Solution -}

circumference = 2\pi \: r  \\ \\ r =  \frac{circumference}{2\pi}  \\  \\r =  \frac{\cancel{122}}{\cancel2 \times  \frac{22}{7} }   \\  \\ r =  \frac{61}{ \frac{22}{7} }  \\  \\ r = 61 \times  \frac{7}{22}  \\  \\ r  =  \frac{427}{22}   \\  \\ r = 19.41 \: inches \: (approx.)

hope helpful :D

Find the limit (Picture Provided)
aev [14]

As long as g(x) (or whichever function appears in the denominator) does not approach 0 as x\to c,

\displaystyle\lim_{x\to c}\frac{f(x)}{g(x)}=\frac{\lim\limits_{x\to c}f(x)}{\lim\limits_{x\to c}g(x)}

In this case,

\displaystyle\lim_{x\to4}\frac gh(x)=\lim_{x\to4}\frac{g(x)}{h(x)}=\frac0{-2}=2

so the answer is B.
