Question

In a circle,if an arc of 5.5 cm.length subtends an angle of measure
$\frac{\pi}{16}$
at the centre,then find the radius of the circle.




​

Answer 1

Step-by-step explanation:

(radius =length/angle)

angle= π/16 (given)

Arc or length is given as 5.5cm

apply the formula (radius= length/ angle)

so,

radius= 5.5/π/16

and L= 5.5cm

angle = π/16

therefore the radius= 5.5/0.196

= 28.06 cm
