Congratulations to all the mathletes who competed at National MATHCOUNTS! If you missed the exciting Countdown Round, you can watch the video at this link. Are you interested in training for MATHCOUNTS or AMC 10 contests? How would you like to train for these math competitions in half the time? We have accelerated sections which meet twice per week instead of once starting on July 8th (7:30pm ET). These sections fill quickly so enroll today!

[list][*]MATHCOUNTS/AMC 8 Basics

For those interested in Olympiad level training in math, computer science, physics, and chemistry, be sure to enroll in our WOOT courses before August 19th to take advantage of early bird pricing!

Summer camps are starting this month at the Virtual Campus in math and language arts that are 2 - to 4 - weeks in duration. Spaces are still available - don’t miss your chance to have a transformative summer experience. There are middle and high school competition math camps as well as Math Beasts camps that review key topics coupled with fun explorations covering areas such as graph theory (Math Beasts Camp 6), cryptography (Math Beasts Camp 7-8), and topology (Math Beasts Camp 8-9)!

Be sure to mark your calendars for the following upcoming events:
[list][*]June 5th, Thursday, 7:30pm ET: Open Discussion with Ben Kornell and Andrew Sutherland, Art of Problem Solving's incoming CEO Ben Kornell and CPO Andrew Sutherland host an Ask Me Anything-style chat. Come ask your questions and get to know our incoming CEO & CPO!
[*]June 9th, Monday, 7:30pm ET, Game Jam: Operation Shuffle!, Come join us to play our second round of Operation Shuffle! If you enjoy number sense, logic, and a healthy dose of luck, this is the game for you. No specific math background is required; all are welcome.[/list]

Khan Academy Math Question
ChaitraliKA   7
N 7 minutes ago by Davin0913
I've been doing Geometry 1 on Khan academy in summer break because I'm taking that class next year in 8th grade.
I've gotten this question wrong at least 6 times now. If she fills 3/4 the height of the cone, then the height would be 7.5. I wanted to know how that should affect the diameter of the new cone. Wouldn't it just be 3/4 of the original diameter which is 6? Then when I go to solve it, I did 6^2(pi) for base area, then multiplied by 7.5 (height), and then divided by 3 because it's a cone. That gave me around 282.74333882308, and rounded to the nearest cubic centimeter, it is 283. Khan Academy says I am wrong. Can someone please explain to me what my error is? Thanks!

See the attachment for the question

I haven't done khan academy in so long but today I had to learn law of sines. I wish khan academy taught competition math because their format, and self paced learning seems a bit better than aops' plus sal's videos for each topic are so good

Solve integration with limits  0 to π  1/(1+tanx)+1/(1+cotx)dx  result is defined as k
N==K+i²+log10(k) +1/4k -sin(1.21×10^-5 k).
Then N yield a value close to following options
A.e(exponential)
B.π
