Question

What is the length of an arc of a circle with a radius of (28 ,cm) with a sectional angle?

a) (14 ,cm)
b) (28 ,cm)
c) (42 ,cm)
d) (56 ,cm)

Answer 1

The length of an arc of a circle cannot be determined without knowing the sectional angle.

Step-by-step explanation:

The length of an arc of a circle can be calculated using the formula:

Arc length = (angle/360) x (2πr)

Given that the radius of the circle is 28 cm and the sectional angle is not specified, we cannot determine the exact length of the arc. The correct answer cannot be determined from the options given.
