A pie costs $12.55. If it has a diameter of 12 inches what is the cost per square inch of the pie.

The cost per square inch of the pie is $0.111 or 11 cents

Step-by-step explanation:

The shape of a pie is circular.

The area of a circle (pie) = πr²

From the question ,

Diameter = 12 inches

Radius = Diameter/2

Radius = 12 inches/2

Radius = 6 inches.

Hence, the area of the pie = π × 6²

= 113.09733553 square inches

A pie costs $12.55

The cost per square inches of the pie is calculated as:

113.09733553 square inches = $12.55

1 square inch = $x

Cross Multiply

113.09733553x = $12.55

x = $12.55/113.09733553

x = $0.1109663631

Approximately

x = $0.111

Therefore, the cost per square inch of the pie is $0.111 or 11 cents

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
