Answer 2

Let us suppose, if—

L = length of the arc, (given→ 40 m)

ϴ = angle subtended by the arc, (given → 25° )

r = radius of the circle, then

L = ϴ x r —————→ (equation)

then change the angle subtended by arc in radian,

i.e., 25° = 25 x ( π /180) radians,

Now, put all the values in above equation,

40 = (25π /180) x r

=> r = (40 x 180) / (25 π)

putting π = 22/7,

=> r = (288 x 7) / 25

=> r = 91.63 m
