### Mensuration question

Question
What is the total surface area of a right circular cylinder in sqcm if its base diameter is 14cm and height is 12cms?
1. 528
2. 308
3. 836
4. 1144
5. 4576

Correct choice (3). Correct answer is 836 sqcm

Total surface area of a right circular cylinder is 2*pi*r*h + 2pi * r^2
Base diameter of the cylinder is 14cm.
Hence, its base radius is 7cm.
Therefore, total surface area is 2*(22/7) * 7 * 12 + 2*(22/7)*7^2
= 528 + 308 = 836

Mensuration is a relatively easy topic to master. Learn all the common formulae for volume, surface area, total surface area of solids such as right circular cylinder, right circular cone, sphere, hemisphere. Solve 10 to 12 questions, at least, for each of the formulae and you should be able to ace questions from this topic.

### TANCET 2009 Announcements

TANCET 2009 will be conducted on May 30th for TANCET MBA and TANCET MCA and on May 31st for TANCET ME/M.Tech

You have just over 2 months from today (March 11, 2009) for the TANCET examination. Actually, if you focus on your preparation earnestly from this moment, you have enough and more time to ace the exam.

An open category student with over 50 marks in the TANCET test in 2008 would have got admission into leading MBA programs that come under Anna University such as Guindy Engineering College, PSG Tech, SSN, TSM Madurai and so on.

Scoring 50 in TANCET is both easy and tough. It is easy if you solve over 1000 math questions, 200 plus Reading comprehension passages, 400 odd sentence correction questions and practice with 4 or 5 mock TANCET tests. It is tough because not more than 25 students have scored that kind of marks in the year 2008.

TANCET, thankfully, has been a predictable exam with clearly set 5 sections, with 20 questions to each section. Break down what you have to learn for each section and spend time wisely - about 3 to 4 hours a day from now to get into the college of your choice.

Lastly, all of us know that the whole world, including India, has been facing a lot of economic challenges. Campus placements are not great this year. Even if you manage to get placed - one is not sure if you will actually convert your offer letter into actually joining the company. So, at least temporarily, the good times (easy placements) are gone. In such trying times, the wise thing to do is to join a PG program and weather the economic downturn in a college / university. When you graduate in 2011, the economy is bound to bounce back and you will most likely be flooded with offers. So, get started with your TANCET Preparation.
