The figure shown represents a piece of land that is in the shape of a quarter circle. If the land is enclosed by a fence, which of the following is closest to the length, in feet, of the fence?

The Central Angle of the Circle is 90.
The length of the Arc = (90/360) * Circumference of the Circle
= 2* pi * 100 / 4 = 2 * pi * 25 = 50 * 3.14 = 157

Length = [(2.pi.r)/4+2r] = r(pi+4)/2=r(3.14+4)/2=r x 3.57
When r is 100, length will be 357

Regards.

A. 278 B. 341 C. 357 D. 400 E. 441

OA ----> C

Please explain.

Wish I got this on my gmatprep. If u know the rules of circles and what not, this is a gimme problem.

Essentially the question is asking us for the perimeter of the quarter circle.

P= Side1+side2+arc length of the 1/4 circle. radius is 100ft so the diameter is 200ft.

Circum=200pi.

to find the arc length take the degrees of the center of the circle given here as 90degrees and divide it by the total degrees of the circle. So 90/360=1/4.

1/4*200pi=50pi

P=100+100+50pi ---> 200+50pi. U must know that pi is rougly 3.14 or even just 3. so 200+150=350. Closest answer to this is C.

OBSERVATION on this Question

i couldn't understand this problem, i saw this problem while i was doing gmat prep 2, i was kind of doing bad in prep test, and the moment i saw this problem, i thought fencing hummm..that seems an easy one--i have to add 100 + 100 + 1/4 of the circumference.

so i quickly applied this formula 2pie r == 2pie100 =200 pie, so i knew i needed one forth of it, so 1/4*200= 50, so far i was kinda going good, but then 100+100+50 = 250 ( and i tried to read the question again but it didn't help, i tried checking my calculation but wasted my time,i didn't want to skip this question cause i knew it was a low difficulty problem, so on actual GMAT the penalty would have been higher, because of that i was little stubborn (though i shouldn't have been),but i was feeling anxious and frustrated at the same time so i ended the test realizing that i had fallen prey to a trap of GMAT test makers, And now in introspect i see how close i was solving this problem all i had to do was to multiply 50*pie(3.14)= 157 + 200=370 answer C.

But i confess, GMAT was able to throw me off balance by an easy problem, and i got panicked, hope so i won't do it in the real test.

You've properly identified the mistake that you made, which is a good bit of self-analysis. Now that you KNOW the mistake, what would you have done differently the first time you tackled this question? I'll bet that you did not write enough on your pad (Did you write down the formula for circumference? Did you write down the pi symbol? Did you write down the numbers? Did you do ANYTHING in your head?). The truth is that the silliest mistakes cost most Test Takers dearly....so you have to do MORE work on the pad to keep those little mistakes from happening. The good news is that the work is actually pretty easy AND it doesn't take too much extra time or effort; now you just have to make that extra note-taking process a part of how you tackle ALL questions.
