A circle of radius 12 units is divided into 8 congruent slices. (How do I solve this?)
a. What is the area of each slice?
b. What is the arc length of each slice?
Picture a round pizza sliced through the middle creating 8 slices. They would be congruent.
a) To find the area of each slice, find the area of the circle and divide this answer by 8. A = pi·r2
b) To find the arc length of each slice, find the circumference of the circle and divide this answer by 8. C = 2·pi·r.
