The fractional form of pi is 22/7.
2*pi*3 = 2*3*(22/7) = 6*(22/7) = 132/7
Now divide (do it manually),
132/7 and you will get 1 into 13 with 6 left over, bring down the 2 and 62/7 = 8 with a remainder of 6. So the answer is 18 and 6/7.
Find the circumference and area of cirlce with a radius of 3 feet.
Let n stand for pi
Circumference=2n x (3)=6 or 18.84 or 18 6/7
I understand how to calulate the circumference. The answer that the book gives of 18 6/7.
I am not clear where the 6/7 is coming from?
I tried it several times and I can't get the 6/7.
