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:
D. 640 m³
Step-by-step explanation:
The height CD of the cone is found using the Pythagorean theorem.
BC² + CD² = BD²
8² + CD² = 17²
CD = √(289 -64) = 15
The volume of the cylinder is ...
V = πr²h
The volume of the cone is ...
V = 1/3πr²h
So, the portion of the cylinder not occupied by the cone is ...
V = (πr²h) -(1/3πr²h) = (2/3)πr²h
V = 2/3(π)(8 m)²(15 m) = 640π m² . . . . . matches choice D
His allowance is $20
He saves 20(.53)
He spends 20(.26)
He uses $2
20 - 20(.53) - 20(.26) - 2 = Money left
