Question

A circle has a radius of 5 and the arc measure is 60. what is the Arc lenght

Answer 1

Answer:

5.23 units

Step-by-step explanation:

Let the length of arc be l

$central \: \angle \: ( \theta) = 60 \degree \\ radius \: (r) = 5 \: units \\ \\ \because \: l = \frac{ \theta}{360 \degree} \times 2\pi \: r \\ \\ \therefore \: l = \frac{60 \degree}{360 \degree} \times 2 \times 3.14 \times 5 \\ \\ \therefore \: l = \frac{1 }{6} \times 31.4 \\ \\ \therefore \: l = 5.23 \: units$
