The difference in area between the top surfaces of the two cakes is 28.26 inches²
<h3>Area of a circle</h3>
where
r = radius
Therefore,
area of top layer = πr²
d = 2r
r = d / 2
r = 8 / 2
r = 4 inches
area of top layer = 3.14 × 4²
area of top layer = 3.14 × 16
area of top layer = 50.24 inches²
area of the bottom layer = πr²
r = 10 / 2 = 5 inches
area of the bottom layer = 3.14 × 5²
area of the bottom layer = 3.14 ×25
area of the bottom layer = 78.5 inches²
Difference in area between the top surfaces of the two cakes can be found as follows:
- 78.5 - 50.24 = 28.26 inches²

The Venn diagram to illustrate this information is given in the image attached.
<h3>What is the
Venn diagram about?</h3>
The number of children who took plantain and beans only are:
Let beans = a
Rice = b
Plantain = P
So: a + b = 24 - 9 - 5 = 10
Note that 24 children took plantain.
9 children took only Plantain.
5 took the 3 food items.
So:
b + c = 18 -2 - 5 = 11
a + c = 21 - 3 - 5 = 13
P∩B = a + 5
= 6 + 5 = 11
R ∩ B = C + 5
=7 + 5 = 12
None of the three items of food =
50 - (3 + 2 + 9 + 6 + 4 + 7 + 5)
= 50 - 36
=14

Answer:
89 employees
3 uniforms left
Step-by-step explanation:
Number of Uniforms per employee = 5
Uniform per pack = 8
Number of packs = 56
Total number of uniforms :
56 * 8 = 448 uniforms
Number of employees who can get uniform :
1 employee = 5 uniforms
Number of employees = 448 / 5 = 89.6
Hence, 89 employees
Yes, (448 - (89*5)
= 448 - 445
= 3 uniforms left
