Question

arc of the length 38 mm at the centre of a circle of
radius 19 mm.
Find the measure of the angle subtended ?​

Answer 1

Step-by-step explanation:

given arc length l=38mm

radius r=19mm

we know that l = 2 π r (θ/360)

if π =3.14

=> θ=(l/(2*3.14*r))*360 (CROSS MULTIPLICATION)

=>θ=(38/119.32)*360

=> measure of subtended angle is 114.765100671

hope you got this let me know for any other quires all the best :)
