This is an area problem where the area of a circle is pi*r^2.
A quiche with a diameter of 12 has an area of pi*6^2 = 36pi
So if it can feed 6 people, then the serving size per person is 6pi per person.
A quiche with a diameter of 10 inches has an area of pi*5^2 = 25pi
If each person requires 6pi worth of quiche, then 25pi/6pi = 4 1/6 people.
So yes, it can serve 4 people.
Answer:
12%
Step-by-step explanation:
28 - 25 = 3
3 / 25 = 0.12
Check: 25 x 1.12 = 28
4x+9=3(x-2)+10
4x+9=3x+4
x+9=4
x=-5
The answer is 1 or A)-5
B is the correct answer
32 / 48 = 2/3
