Answer:
A; The cost is $0.07 per 
Step-by-step explanation:
In this question, we are asked to calculate the cost of the Chicago pizza per square inch rounded to the nearest cent.
Firstly, we will need to calculate the area occupied by the 14 inch medium pepperoni pizza made by Chicago pizza
Since the pizza is circular in shape, we use the formula for the area of a circle to calculate its area in square inch
Mathematically, the area of a circle is equal to π
. Here, our r is half the size of the pizza as the 14 inch represents the full length of the pizza across the center of the pizza = 7 inch
The area is thus = 22/7 × 7 × 7 = 154 
Now, since the full pizza costs $10.49, the cost of the pizza per
is 10.49/154 = 0.068 = $0.07 per

Answer:
15
Step-by-step explanation:
Finding total number of pupils(y)
3/y x 360°=27°
3x360°/y=27°
1080°/y=27°
1080°=27°y
1080°/27°=27°y/27°
40=y
Number of pupils who said that Maths was their favorite (z)
z/40x360°=135°
360°z/40=135°
360°z=135°x40
360°z=5400°
360°z/360°=5400°/360°
z=15
