Question

find the angle in degree substended at the centre of a circle by an arc whose length is 15 cm , if the radius of thr circle is 25cm​

Answer 1

To Find :

• Angle in degree substended at the centre of a circle by an arc

Solution :

• Length of arc = 15cm
• Radius of circle = 25cm

By using Formula :

⠀⠀⠀⠀⠀ θ = l/r

Where,

• l = length of arc
• r = radius of circle

θ = 15/25

θ = 3/5

θ = 0.6 radian
