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.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

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

Did you mean the following formula ?

Area of sector=θ2ππr2\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 .

@A Former Brilliant Member I am sorry for Confusing you. . I am looking for the formula for the Circular segment.

hazel desuyo - 4 years, 6 months ago

Log in to reply

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

A Former Brilliant Member - 4 years, 6 months ago

Log in to reply

@Hazel Desuyo

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 .
