Question

A circle of radius 16 units is divided into 8 congruent slices.

What is the arc length of each slice?

4π units

3π units

2π units

π units

Answer 1

4π

Explanation:

Circumference = π X D (D = diameter = 2 X radius).

Diameter = 32.

Circumference = π (32) = 32π.

Divided into 8 slices = 1/8 of the circumference = 32π/8 = 4π.
