Question

The length of arc which subtends an angle of 33°15' at centre of the circle whose radius is 5 cm is:

(a)

$\frac{209}{75}$

(b)

$\frac{209}{72}$

(c)

$\frac{219}{72}$

(d)

$\frac{219}{75}$

​

Answer 1

Answer:

ç) 209/72

Step-by-step explanation:

length of arc =

$\frac{ {x}^{o} }{360} \times 2 \times \pi \times r \\ = \frac{33.15}{360} \times 2 \times \frac{22}{7} \times 5 \\ = 2.89 \: cm$
