The pipe will have an outside diameter of 1.5+.25+.25 = 2".
A pipe with an outside diameter of 2" has an outside circumference of 2"*Pi.
2"*3.142 ~= 6.284" or about 6 1/4"
diameter X pi = circumference circumference X height = area
The diameter of a circle with a circumference of 2.75 inches is: 0.875 inches (circumference divided by pi = diameter).
Diameter = 11.14 inches (approx) ~ Circumference can be found by pi * diameter.
Circumference = pi*diameter = 87.96 inches.
The circumference of a circle with a diameter of 45 inches is 141.37 inches.
The circumference is about 6.28 (2 pi) inches. This is just addition of the thickness of two opposite walls (1/4" x 2 = 1/2) to the inside diameter (1 1/2 + 1/2 =2), then multiplied by pi.
diameter X pi = circumference circumference X height = area
If a circle has a circumference of 6 inches the diameter is: 1.91 inches (circumference divided by Pi = diameter).
If a circle has a diameter of 24 inches its circumference is: 75.4 inches (diameter x Pi = circumference).
If the circumference of a circle is 10 inches, the diameter is: about 3.183 inches. (circumference divided by Pi = diameter)
If a circle has a diameter of 12.8 inches its circumference is: 40.21 inches (circumference = diameter x Pi).
The circumference of a circle if its diameter is 20 inches is: 62.83 inches (diameter x Pi = circumference).
If the circumference of a circle is 75 inches, the diameter is: about 23.87 inches. (diameter = circumference divided by pi).
The circumference of a circle, if the diameter is 9.5 inches, is: 29.85 inches (diameter x Pi = circumference)
If the circumference of a circle is 28 inches the diameter is: 8.913 inches (circumference divided by Pi = diameter).
The diameter of a circle with circumference of 25.56 inches is: 8.136 inches (diameter x Pi = circumference).
the answer for the area is 615.8 and the answer for the circumference is 88 inches when you round!!!!
