We are asked to calculate the circumference of the two circles; all the required information is given to us.
[tex]\triangle~\fbox{\bf{KEY:}}[/tex]
- The formula for the circumference is: [tex]\mathrm{C=\pi d}[/tex].
'
In this formula,
[tex]\star~\mathrm{C=Circumference; \\ \pi =pi,\;which\;is\;3.14; d=diameter}}[/tex]
------------------------------------------
Question #1
------------------------------------------
Circumference of Circle
Given value(s):
So to solve for circumference, we should substitute 10 for y, which gives us:
[tex]\mathrm{C=10\pi}[/tex]
Circumference:
[tex]\bigstar~\mathrm{\underline{C=31.4\:cm}}[/tex]
------------------------------------
Question #2
-------------------------------------
This time, the diameter is 6 units. We follow the same steps to find the circumference:
[tex]\mathrm{C=6\pi }[/tex]
Upon multiplication,
[tex]\bigstar~\mathrm{\underline{C=18.8\:cm}}[/tex]
Hope it helps you out! :)
