Find the circumference answer with solutions 1. d = 5.5cmC=________2. d = 8mC=________3. d = 5.8mC=________I need this today so pls help!Quick answer= Perfect RatingToo complex= Reported

Answer 1

The cricumference formula is given by:

$C=\pi *d$

where C denote the circumference, d the diameter of the circle and Pi is the constant equal to 3.14.

Case 1.

In this case, d=5.5 cm, then by substituting this value into the formula, we get

$\begin{gathered} C=3.14*5.5 \\ C=17.27\text{ cm} \end{gathered}$

Case 2.

Now, by substitutinfg d=8m, into the circumference formula, we get

$\begin{gathered} C=3.14*8m \\ C=25.12m \end{gathered}$

Case 3.

Finally, by substituting d=5.8m into the formula, we obtain

$\begin{gathered} C=3.14*5.8m \\ C=18.212\text{ m} \end{gathered}$

In summary, the answers are:

$\begin{gathered} 1)\text{ C=17.27cm} \\ 2)\text{ C=25.12 m} \\ 3)\text{ C=18.212 m} \end{gathered}$
