Question

find the length of an Arc of a circle whose central angle is 45 degree and radius is 56 CM

Answer 1

Hey ......

This is your answer

Length of the arc when angle is given = 2×pie×r× theta upon 360°.

= 2×22/7×28×45/360

= 2×22×4×1/8

= 8×1/8×22

= 22cm

Hence the length of the arc is 22cm.
