Answer: The length of an arc is given by the formula:
length of arc = (central angle/360) x 2πr
where r is the radius of the circle.
Substituting the given values, we get:
length of arc = (225/360) x 2 x 3.14 x 5
= 0.625 x 31.4
= 19.63 cm (rounded to the nearest hundredth)
Therefore, the length of the arc with central angle of 225° and radius of 5 cm is approximately 19.63 cm. Option (D) is the correct answer.
