Question

What is the length of AR if the radius of the circle is 6 cm?

Answer 1

Explanation:

`arc \: length \: = (theta)/(360) * 2\pi \: r \\ here \: theta \: = 105 \: degrees \: \: \: \: and \\ radius \: = 6 \: cm \\ on \: substituting \: the \: values \: in \: formula \\ = (105)/(360) * 2\pi \: * 6 \\ = (105)/(360) * 12\pi \\ = (105)/(30) * \pi \\ = 3.5 * \pi \\ = 3.5 * 3.14 \\ = 10.99 \\ arc \: length \: = 11.0 \: \: (approximately)`
