Question

Use the arc length formula and the given information to find r. S = 16 cm, = 48; r = ? (1 point)

Answer 1

In the arc angle is 360°
the perimeter of the circle 2|_| r
the arc angle = 48°and arc length as 16 cm
through simple ratio and proportions equation
we can write,
360/48 = 2|_|r / 16

= 7.5 * 16 = 2|_|r

= r = 19.09 cm
