Given,
The radius of the cylinderis 5unit.
Required
The measure of CD.
The length of the CD is equal to the circumference of the base of circle.
So, the length of the cylinder is,
[tex]\begin{gathered} Length=2\pi r \\ =2\times\pi\times5 \\ =10\times\pi \\ =10\pi \end{gathered}[/tex]
Hence,the length of CD is 10 pi.
