Question

(c) the radius of circle is 5 centimetre .the length of the arc that will subtend an angle of 15 degree at the centre is
1. 1.3cm 2. 1.5cm. 3. 4.5cm. 4. 2.3cm​

Answer 1

Answer:

1.30833333

Step-by-step explanation:

See it's given that radius = 5cm

Angle at centre is 15

Thus Length of Arc =

• (Angle at centre* Circumference of circle)/360
• (15*2*pie*r)/360
• (15*2*3.14*5)/360 ( pie = 3.14)
• 471/360
• 1.308333 cm

Thus Length of Arc = 1.3 cm
