Answer 1

Answer:

Below in bold.

Step-by-step explanation:

i. area = πr^2 = π9^2

= 81π

ii. There are  360/60 = 6 parts.

If 1 part goes to 3 people there are 18 people.

iii. The weight of one 60 degree piece = 3600 / 6 = 600 g.

So each person gets 600 / 3 = 200g

iv. The perimeter of the top of the cake = π * diameter

= 18π.

The length of the arc of a slice = 18π/ 6 = 3π

So the perimeter of the top of each 60 degree slice

= 2(9) + 3π

= 27.42 inches.

v.  200 * 20

= 400 g

= 4 kg.
