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.

Okay so the area is in sq ft. Convert that to sq meters = 4.45935. Multiply this by 28 = <span>124.8618. So the cost would be $124.87 (approximately) to cover the whole thing.</span>
Given that energy produce by working out by the human body is 2,400 btu per hour per persons. 6 football player
v = 12 ft x 18 ft x 10 ft
E = ( 2400 Btu/ person hr) ( 2 hrs ) ( 6 persons ) / ( 12 ft x 18 ft x 10 ft )
E = 13.3 BTU / cu ft is they energy of 6 football player produce in working out for 2 hrs
