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:
-1
Step-by-step explanation:
2 × (-1²) + 1 = 2 × (-1) + 1 = -2 + 1 = -1
A=pi r^2
then use your rate of $4.60/m^2 and multiply that by your area.
A = 3.14 (.8^2)
Cost = 2.01 m^2 $4.60/m^2 = $9.24
So your answer would be B

<span>0.4×0.4×0.4 is equal to 0.4 to the third power, or 0.4</span>³
To convert to exponential form, count how many times the number is multiplied by itself and make that number the exponent. In this case, the 0.4 is multiplied by itself 3 times, so our exponent is 3.
Answer is 0.4³
