Question

What Is The Angle Subtended At The Centre Of A Circle Of Radius 5 Cm By A Chord Of Length 5 Cm Arc Of Length 5 Cm

Answer 1

Answer:

1 rad

Step-by-step explanation:

Angle (in rad) =( Arc length) /( radius)

arc length =5 cm

radius =5cm

Answer 2

Answer:

The angle subtended at the centre of circle =$57.27^{\circ}$

Step-by-step explanation:

We are given that a circle

We have to find the angle subtended at the centre of circle

Length of an arc of circle =5 cm

Radius of circle = 5 cm

Length of chord of a circle = 5 cm

We know that $\theta=\frac{l}{r}$

Where $\theta$=Angle subtended at the centre

l=Length of an arc

r=Radius of circle

Substituting all values in the given formula

Then we get $\theta =\frac{5}{5}$

=1 radian

$\theta =57.27^{\circ}$

Degree measure =$\frac{180}{\pi}$

Hence, the angle subtended at the centre of circle =$57.27^{\circ}$
