Answer:
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
Answer:
2.4 hours
Step-by-step explanation:
Because 1 hour Randy clean 1/4 of the room and Trey is 1/6. So we add both together and get that they clean 5/12 of the office in one hour. So 2.4 hours is the greatest amount of time it would take them to clean offices together
D) 1:6 because she brought 6 paintbrushes and 36 tubes of oil paint, and we can simplify that to 1/6
