"2 times pi times r", which can be written as "2*pi*r", represents the circumference of a circle. This is the distance around the circle (aka perimeter)

r is the radius of the circle

if you know the diameter then you can divide the diameter in half to get the radius (example: diameter is 10 so the radius is 5)

Jolie can read around 14 sentences per minute of her current novel. She wants to finish her reading before the movie comes out n
vladimir1956 [14]
This is what you would do
120 x 17= 2040
Or you could do 12 x 17 then, add a zero to the end of it.
Then you would divid from what you got when you did 120 x 17 by 60
That should give you the answer. 
Hope this helps if im not mistaken it should be 34 

2040 <span>60 </span>= 34

34 = 340 to the nearest tenth

34 = 34 to the nearest hundredth

34 = 34 to the nearest thousandth

= 0 to the nearest tenth

= 0 to the nearest hundredth

= 0 to the nearest thousandth

Murljashka [212]
So Marci's sore was 45 because every percent has to be out of 100 so to get it to 50 you divide by two so 90 / 2 = 45. And 45-39 = 6 

Marci got 6 more correct then Donovan.
