41) Circumference of a circle is 2*pi*radius, or pi*diameter.
Diameter given is 0.5cm, so circumference is 0.5pi, approximately 1.57cm.
It says scale is 1 cm to 2.5ft. Use dimensional analysis. You can multiply by 2.5ft / 1 cm because it equals 1, and multiplying by 1 doesn't change the value (just the units here).
1.57cm * 2.5ft
-------- = 3.925ft
1 cm
C) 4 feet

3x = 2x + 6 subtract 2x brom both sides (second)
3x -2x = 2x -2x +6
5x = 6
