Question 274224: I think this is the right topic but I'm not sure sorry if its not..
Use 3.14 for Pi. Find the circumference of each circle to the nearest tenth.
1.r = 10 m
a.C = 30.1 m
b.C = 314 m
c.C = 62.8 m
d.C = 20 m
2.d = 14 ft
a.C = 153.9 ft
b.C = 44.0 ft
c.C = 28.0 ft
d.C = 62.3 ft
thanks for your time and help.

where is the measure of the diameter of the circle. But where is the radius of the circle. Hence:



Put in the values and do the arithmetic.

However, note that technically speaking, NONE of the given answers are correct.
That is because all of the answers use an equals [ = ] sign. Since is a transcendental irrational number that cannot be represented exactly with a decimal no matter how many decimal places are used, any decimal representation is an approximation and the appropriate symbol is: .
