Question

find the length of arc of the circle which subtend of angel 108°at the centre if the radius of the circle is 15 cm​

Answer 1

Answer:

Step-by-step explanation:

108/360×2×22/7×15

=0.3×2×3.14×15

=28.2 cm

Answer 2

Answer:

theta = 108 °

radius 'r' = 15 cm

we know that,

• length of the arc = theta/360 × 2πr

= 180/ 360 × 2×3.14×15

= 1/2 × 2 × 3.14 × 15

= 3.14 × 15

Answer = 47.1 cm (approx)
