Question
The length of an arc is 11cm. If the radius of the circle is 21cm, find the angle subtended at the centre
Answers
GPT 3.5
To find the angle subtended at the center, we can use the formula:
Angle = (Arc length / Radius) * 180°
Substitute the given values:
Angle = (11 / 21) * 180°
Angle = (0.5238) * 180°
Angle = 94.25°
Therefore, the angle subtended at the center is 94.25°.
Angle = (Arc length / Radius) * 180°
Substitute the given values:
Angle = (11 / 21) * 180°
Angle = (0.5238) * 180°
Angle = 94.25°
Therefore, the angle subtended at the center is 94.25°.
