Maths Academy, is a Maths centric institute formed in 2013 when a batch of seven students with complaints of nervousness and poor track record passed out with marks in the range of 65%- 72%. It is formed with the sole intention to get satisfaction out of success stories of such students who have uneasiness with Maths.

Our teaching is styled to help everyone secure extra confidence through fast solving tricks, solving a particular question in as many different ways as possible, out-of-textbook method of guessing and approximation for Olympiads and entrance examinations, along with practical understanding of terminologies with their everyday application.

It is founded by me, Gautam Pal. A full time MBA from IMT Ghaziabad batch of 2010 and a B.E from NIT Durgapur of 2005, I have worked in IT and Manufacturing sector when the drive to do something for the younger generation inspired me to start my teaching journey. In a space of one year, I interacted with students across various boards and found out that Maths if taught with fun, practical insight, logical methodology and patience can be appreciated by all minds - rich or weak.

At Hello Maths Academy, we take academic courses of class V to X across various boards such as CBSE, ICSE, IB and State Board. Every child is taught his/her current year syllabus in addition to the earlier class content as revision. A bit of next year syllabus is also covered for topics that are going to be there for next year.

Teaching Experience in detail in Class 10 Tuition

Teaching Class X Mathematics is a process where a child is expected to have his fundamentals on arithmetic, algebra and geometry pretty robust. It is like constructing a building on a sound foundation. So my method involved around the why and how of Mathematics at this point. I stress upon the why and how so that a child doesn't have to be dependent on memorizing the formulas blindly without understanding the logic behind it. Continuous practice is the next approach to finetune his preparation for the final exam.

In Class 6 children are exposed to ideas which are to be continued for further 2 years and also to ideas which are to be the foundation basis for higher concepts in future. So I try to solve them a Maths question in as many different ways as possible so that they realize the inter-connectivity between different ideas and also realize that a Maths concept can be tackled by various methods but give them the freedom to solve the question as per the method they like. Also, giving real life examples is necessary so that they don't feel that Maths is a abstract subject.

In Class 7 children are mature enough to be exposed to basic questions and Olympiad questions. So after telling them the basic idea of a concept I give them Olympiad level questions so that they try to put their efforts into applying the basic ideas in solving the tough questions. Most of the time they are not successful, but that is where I tell them that I was also like them and only became better by understanding the problem and the method to solve it. So encouragement is very vital at this stage. Also, I try to solve them a Maths question in as many different ways as possible so that they realize the inter-connectivity between different ideas and also realize that a Maths concept can be tackled by various methods but give them the freedom to solve the question as per the method they like.

Diameter of the cone = 10.5m (Radius of the cone = 5.25m)

Height of the cone = 3m

Volume of the cone = (πr²h)/3

∴ Volume of the cone = (π x 5.25² x 3)/3 = 86.625m³

The heap is to be covered by canvas to protect it from rain and we have to find the area of the canvas required. So, that means, we have to find the lateral surface area.

Lateral surface area of the cone = πr√r² + h²

∴ Lateral surface area of the cone = π x 5.25√5.25² + 3² = 99.77m²

∴ The area of the canvas required = 99.77m²

(i) In ΔAMC and ΔBMD,

AM = BM (M is the mid-point of hypotenuse AB)

∠AMC = ∠BMD (vertically opposite angles)

CM = DM

ΔAMC ≅ ΔBMD by SAS Test of congruency

(ii) ∠ACM = ∠BDM (corressponding angles of congruent triangles)

Also, ∠ACM and ∠BDM form alternate interior angles with CD as the transversal.

So, AC parallel to BD.

So, ∠ACB and ∠DBC form co-interior angle with BC as transversal.

So, ∠ACB + ∠DBC = 180° (co-interior angle adds up to 180°)

∠ACB = 90° (It is given that in triangle ABC, right angled at C)

So, ∠DBC = 90°. So, ∠DBC is a right angle.

(iii) ΔAMC ≅ ΔBMD by SAS Test of congruency

∴ AC = BD (corressponding sides of congruent triangles)

Now, in ΔDBC and ΔACB

BD = AC

∠DBC = ∠ACB (both are 90°)

BC = BC (common side)

∴ ΔDBC ≅ ΔACB by SAS Test of congruency

(iv) ∴ DC = AB (corressponding sides of congruent triangles)

∴ DM + MC = AB

∴ MC + MC = AB (It is given, DM = MC)

∴ 2 MC = AB

∴ MC = 1/2 AB
