a.
To find the maximum and minimum circumference
a.

Answer to Problem 33PPS
Minimum circumference is 25 inches and maximum circumference is 31 inches
Explanation of Solution
Given information:
Diameter is 8 to 10 inches
Calculation:
For minimum circumference,
Circumference=
Solving,
Circumference=
So, circumference=
Substituting value,
Circumference=
Minimum circumference is 25.12.
For maximum circumference,
Circumference=
Solving,
Circumference=
So, circumference=
Substituting value,
Circumference=
Maximum circumference is 31.4.
Hence minimum circumference is 25 inches and maximum circumference is 31 inches.
b.
To find the range of possible areas
b.

Answer to Problem 33PPS
Range of area is 50.24 to 78.5 inches2
Explanation of Solution
Given information:
Diameter is 8 to 10 inches
Calculation:
Radius=
So,
radius is 4 inches to 5 inches
Area for minimum,
Area=
Substituting values,
Area=
Solving,
Area=
Minimum area is 50.24 inches2.
Area for maximum,
Area=
Substituting values,
Area=
Solving,
Area=
Maximum area is 78.5 inches2.
Hence, range of area is 50.24 to 78.5 inches2.
