3. find the diameter of a circle with a circumference of 50 mm. round your answer to the nearest tenth.
16.0 mm
26.4 mm
8.4 mm
33.5 mm

1) Equation that you need is: 

C = 2πr 

The diagram shows that the radius is 3.5, so plug it in the equation and solve for C 

C = 2(3.14)(3.5) 
C = 21.98 
Rounded to tenth: 22.0

2) The equation you need to know here is: 

A = πr² 

The diagram shows diameter is 12, so radius is 6. Plus in the info, we have and solve for A 

A = 3.14(6)² 
A = 113.04 
rounded to tenths: 113.0

3) Find the diameter of a circle with a circumference of 50mm. 

C = 2πr 
50 = 2(3.14)r 
50 = 6.28r 
r = 50 / 6.28 
r = 7.96 

You were asked to find the diameter, so double that, then round it to tenths: 

d = 2r 
d = 2(7.96) 
d = 15.92 
Rounded to 15.9mm 

29. because you will divide each number of months by 12 to find the number of years. which would mean, 5, 12.5, 16, 45, 50, 72.5. which is crazy. anyhow, i think you find the median in the middle. and yea hope your test goes good

I’m confused as to what you are asking 66 2/3 percentage wise
