Question

What is the length of arc S shown below

Answer 1

s= 11.3 units

Explanation:

`s= ( (3\pi)/(5) )/(2\pi) * 2\pi \: r \\ \\ s = \frac{{3\pi}}{5 * 2\pi} * 2\pi \: * 6\\ \\ s= \frac{{3}}{5} * \pi \: * 6 \\ \\ s= \frac{{18}}{5} * 3.14 \\ \\ s= \frac{{56.52}}{5} \\ s= 11.304 \: units \\ \huge \red {\boxed{s= 11.3 \: units}}`

Answer 2

Answer:
`(18\pi )/(5)`
