Question

in a circle of diameter 28cm, if an arc subtends an angle of 30˚ at the centre , then what

will be the length of arc.​

Answer 1

Diameter = 28cm

Radius (r) = 14 cm

Lengh of arc =

$\frac{30}{360} \times 2 \times \frac{22}{7} \times 14$

$\frac{1}{12} \times 2 \times 22 \times 2$

$\frac{44}{6}$

22/3

7.33 square cm (Approx)

Answer 2

Answer:

30/360*2π(28/2)

1/6*22/7*14

22/3=7.3
