Question

(2) The measure of an arc of a circle is 60° and its radius is 15 cm. Find
the length of the arc. (i = 3.14)​

Answer 1

Answer:

15.7 cm

Step-by-step explanation:

Radius=15cm

so, perimeter will be=(2×15×3.14)cm or, 94.2 cm

now, For 360° the arc is=94.2 cm

or, For 1° the arc is= (94.2/360) cm

or, For 60° the arc is= (94.2/360)×60 cm

=15.7 cm
