Multiply 8 with pi since the equation for circumference is 2pi(r), or d(pi). The answer is 25.13
Answer:
percentage error = 12.28%
Step-by-step explanation:
5 x 0.14 = 0.7
5 x 1.14 = 5.7
as increase is not the same as error decrease.
We use the same numbers 12.28% = 0.1228.
5.7 x 0.1228 = 0.69996 = 12.28%
5.7 - 0.69996 = 5.00004 foot. As decrease.
And find it is correct.
His error therefore was 12.28% out.
As we work the first numbers 5.7 and can only x by a number to see 5ft
We take 5.7 x 0.1228 and find 0.69996 when taken from 5.7 ft. is unmistakably 5 foot. (5.00004) ft.
Ok, lets start with the basics:
the distibutive property is very simple once you get used to it!
distibutive just means when you both multiply and add in the same problem( mostly with Peranthisys.
lets start with a basic problem:
5(3+4)
because you have the five bumped up against the peranthysys, you "distribute" the problem (you multiply 5 by the numbers present.
for example, once you multiply, you should get this:
5(3+4)
15+20
all i did was multiply the numbers inside! now the Peranthisys disapear!
now all you do is add!
15+20=35
35 is your answer.
NOTE:This is just simple distributing, once variables get involved, it changes a little...
Hope this helps!!!
