Question

In the given figure,area of the circle with centre O is πcm². What is length of the minor arc PQ?
Please answer me this question!!​

Answer 1

Answer:

we know that,

theta/360°× 2 × (pie) × r = length of arc

=> 30°/360° × 2 × 22/7 × 1

=> 1/12 × 2 × 3.14 × 1

=> 0.523

Answer 2

HERE IS UR ANSWER

$_____________________________$

$length \: of \: arc = \frac{\theta}{360 \degree} \times 2 \times \pi \times r \\ = \frac{30\degree}{360\degree} \times 2 \times 3.14 \times 1 \\ = \frac{1}{12} \times 2 \times 3.14 \\ length \: of \: pq = 0.523$
