What is the circumference of a circle if the radius is 6.7500 Use 3.1415 as pi
Round to the nearest 1000th

Circumference of a circle   is C=2 pi r =2(3.1415) (6.7500)=42.4575

Step-by-step explanation

C= 42.4575 , now round to the nearest 1000th...= 42.5000

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
