Please help I don’t understand this

Answer 1

Answer:

area = 19.2325

perimeter = 19.495

Step-by-step explanation:

circular cake diameter = 14 in

radius = d / 2 = 14/2 = 7 in

cut into 8 equal slices

so area of 1 slice = Total area / 8

A = pi * r^2

= 3.14 * 7 * 7

= 3.14 * 49

= 153.86

so area of one slice = 153.86/8 = 19.2325

so for perimeter also it is 1/8 of the total cake perimeter and two times the radius

cake perimeter = P = 2*pi*r

= 2 * 3.14 * 7

= 43.96

so perimeter of slice = 2*r + 1/8 * 43.96

= 2*7 + 1/8 * 43.96

= 19.495
