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

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser

step-by-step explanation:

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.
