ERROR ANALYSIS Describe and correct the error in finding the circumference of $\odot \mathrm{C}$ .

Ali Soave · Accepted Answer

So this person used the formula of circumference as his two pi tens radius. However, we are told the diameter of the circle is nine. So, in fact the radius wouldn&#x27;t be nine. It would be half of that, which is 4.5 and multiply times too. That makes nine, so that

we&#x27;re going to calculate the absolute and relative mirrors off approximating pie by three point Fortin. We know that the absolute you&#x27;re is to find us the absolute value off the difference between the except value, excitable by minus he approximating valley. So in this case is equal to the absolute value of pi minus 3.14 and Teoh approximate thes after the bureau we get to use anyway and ah, much better approximation by because by Sandy Russia lovers over because in friendly, many decimals without any period Ah, that repeats intestinal fraction decimal part of the number. So using a much better approximation of by we consider this separate, humid legal too. One point 59 26 five 35 89 Date time Stand to the negative three. Now the relative era is equal to the absolute era Torrisi after the value of X minus C over d absolute value of the except a value that is everybody of X. So he&#x27;s sequel in this case to the absolute value by minors. Three boy 14 over the two body of by. That is fine And again we can and we can calculate thes relative. You&#x27;re exactly, because by self Russia number. So you get to use an approximation of much better approximation by to estimate is relative mirror and we find on December similarly could see five point Cirrus seven time stand to the negative four. So decide is Artie absolute here and relative era off approximating Bye bye. The number three Boyne 14.

Okay, this is problem 12. You are being asked to describe and correct the error and finding the length of Arc G h in the problem. They&#x27;re saying that our Klink of G H is equal to the measure of G H arc gh times two pi r. The air that they&#x27;re making here is they are not dividing the measure by 360 degrees. So, upon doing that, that&#x27;s going to change and results, and you&#x27;re gonna end up with Let&#x27;s see, we need to. They had the measure of art. GH is 75. We need to divide that by the 360 and multiply it by to pie. And that radius was five. So we need to multiply that by five. So when we do that, our answer is going to come out to be. It will be a 750 all over 3 60 pie. You can reduce that down. We can divide both of those by 30 to make it smaller, and it&#x27;s gonna be 25 over 12 times pi. And this is gonna be centimeters. So this is our answer right here.

Heather Zimmers · Answer

in this problem. Our job is to find the air and correct it. So we start with the quadratic equation and then it&#x27;s factored. And then each factors said equal to zero. Well, the problem is right here because it didn&#x27;t have equal zero there. We needed to say equal zero before we consider each factor equal to zero. So what would we do instead? Starting over with our equation? We was attract 20 from both sides. That gives us equal to zero. Then we would factor it interns out of factors into two X minus five times X plus four. And then we would set each factor equal to zero and solve each one. We would get five halves or negative for.

Okay, So for this problem, uh, we are given a diagram of a circle that shows that the diameter of this circle is 10 over Paice and meters. We&#x27;re told to find that the circumference of that circle, Uh, and early around in the chapter, we were taught that one way of finding circumference is that conference is equal to hi times the diameter of this circle. So for this problem, all we have to do is, uh, plug the diameter of the circle into this equation. And after we my apologies. After re plug in D family to this equation, we just solved high times one over pies, ones that we just get 10 centimeters and that is the circumference is

Cory Kuzinski · Answer

All right. So before we correct the mistake in the diagram, how about we actually get the right solution for so negative? 36 equals X over nine. So since exes being divided by nine, we want to do the opposite of that. To get rid of that, divided by nine now would be to multiply by nine. So end up with nine over nine, which is one and one times x is just x. So since we multiplied by nine on the right, we also have to multiply by nine on the left. We have a positive times, and negative is a negative. Nine times 30 is, um, 279 times six is 54. So 270 plus 54 is 324. You don&#x27;t understand what I did right there. I mean, obviously, we can just grab a calculator. So negative £324 are negative. 324 is the correct answer. Um, so if you look at what the person did in the diagram, um, they did negative. 36 equals X over nine, but they multiplied by, Ah, one night on. And if you multiply by 1 90 Don&#x27;t get X by itself. What you get is, um X over 81 equals negative four because nine goes in tow. Negative. 36 negative four times. So that isn&#x27;t the answer That doesn&#x27;t get X by itself. In fact, it makes the fraction over here even uglier. So now you have to multiply both sides by 81. And that would give you negative 3 24 if you did it.
