Estimate the area of a circle with a radius of 16 meters use 22/7 for pi
A) 62 square meters
B) 531 square meters
C) 805 square meters
D) 1,608 square meters
Can someone explain to me how to do this?

  1. Area = Pi x radius x radius
    = 22/7 x 16 x 16
    But you were asked to ESTIMATE...
    which means use nice numbers
    Nice numbers could be (20 x 20 x 20 ) divided by 10
    =8000 divided by 10
    = 800
    That is an estimate : ) thus C)

  2. Looks like a question from the 50's, nobody uses 22/7 anymore in the days of calculators ...

    area = πr^2, r = 16 and π = appr 22/7 = appr 3
    so what is 3(256) ? , in my head , 3(250) = 750

    using 22/7 ---> 256(22/7) = 804.57 , since we are estimating, did they
    expect to get that answer not using a calculator?

    real answer = 256π or 804.247...

  4. Then just go with Ms. Pi solution, after all we got the same result.
    My rough calculation ended up with 750
    In the answer group the closest to that was 805
    My point was that to get that 805, they must have used a detailed calculation,
    which sort of negates the concept of estimation.

  7. Two teaser trailers were released for the film that feature Seinfeld dressed in a bee costume, trying to shoot the film in live-action. Eddie Izzard portrays the director, and Steven Spielberg suggests to Seinfeld in the second trailer to just do it as a cartoon. Upon the release of the first trailer, it was announced that three of the live-action teasers would be released in total.[4] In the second trailer, Steven Spielberg is taking a picture of himself and an assistant director, referencing the camera gag Ellen DeGeneres pulled on him during the 79th Academy Awards. After Seinfeld fails to do scenes in live-action, Spielberg suggests Seinfeld that the film can just be made as a cartoon. One of the crew members announces that the film is a cartoon, having the crew leave the stage studio. The trailer finally shows the movie as an animated CGI feature. Also in the second trailer, the bear that jumps out at Barry is Vincent the Bear from Over the Hedge, another DreamWorks Animation SKG movie.[5][6]

    The third trailer was released with Shrek the Third, but this was an animated teaser. The fourth trailer was released on the Bee Movie official website, and revealed most of the film's plot.[7] In addition, two weeks before the release, NBC aired 22 behind-the-scenes skits called "Bee Movie TV Juniors," all of which are staged and tongue-in-cheek in nature.[8] The popular internet site Gaia Online featured a great deal of promotional material for the film.[9]
