# Mathematics

Math is not making simple things complicated but making complicated things simple

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

Yeah , exactly ! I don't understand why there are people out there who can't understand this simple fact .

hi there. are you good at solid mensuration?

- 5 years, 2 months ago

You mean something on the lines of 3D geometry ?

- 5 years, 2 months ago

yes, cause i really find it hard especially the formula for the circular sector and segment

- 5 years, 2 months ago

I am not that Good in Math. . .

- 5 years, 2 months ago

No problem ! Maths is an easy subject which can be learned by any person by themselves :) Just keep working on it .

- 5 years, 2 months ago

Thank you. are you living in India?

- 5 years, 2 months ago

I hope I can Be as smart as you.

- 5 years, 2 months ago

I'm not smart -_-

There are many smarter people out here on B'ant . The list is endless !

- 5 years, 2 months ago

Come on I know you are. . .

- 5 years, 2 months ago

hey

- 4 years, 4 months ago

hi. what math book will help me to understand more about math?

- 4 years, 4 months ago

Yeah. I am an Indian .

- 5 years, 2 months ago

- 5 years, 2 months ago

Not yet .I am going to write the entrance exams in a few days . The first of which is on the 4th of April .

- 5 years, 2 months ago

You can Do it!!. . . what course are you going to take?

- 5 years, 2 months ago

It'll be great if I could get to study Computer Science .

- 5 years, 2 months ago

yeah. wish you luck. thank you for helping me. I think it's time to wave goodbye. thank you for your time.

- 5 years, 2 months ago

Thank you for being kind. I'll pray for you to pass the examination.

- 5 years, 2 months ago

Thanks $\ddot\smile$

Can you please elaborate a bit ? I didn't get what you meant !

Did you mean the following formula ?

$\text{Area of sector} = \dfrac{\theta}{2\pi} \pi r^{2}$

And likewise the formula for segment can be got by subtracting it from the triangle formed by the chord with the radii .

I am confused by your comment since a segment is a segment in both 2D as well as 3D .

- 5 years, 2 months ago

I am sorry for Confusing you. . I am looking for the formula for the Circular segment.

- 5 years, 2 months ago

Do you want the formula for calculating the area of a circular segment ?

- 5 years, 2 months ago

To get the area of the minor segment AB , you'll first calculate the area of the sector AOB using the formula that i had provided earlier . Now subtract the area of the triangle from the area of the sector to get the area of the segment .

If you want to get the area of the major segment , then you'll have to subtract that area from the area of the circle .
