Question

by walking 25π metre on a circular path of 100 m radius , value of angle subtended at centre in radian will be​

Answer 1

Answer:

circumference of a circle

$2\pi \: r$

circumference = 2* π*100 = 200π

distance travelled = 25π

so 1/8 part of circumference is travelled

angle subtended to centre =

π/8
