Try solving it first then post your solution here

Hi kchua:

The "sector" is an area.

The "segment" is also an area.

There are formulas for each of these calculations.

Do you have a textbook? (If not, you may search at Google.)

Please show us your efforts or explain where you're stuck.

Cheers :cool:

The "sector" is an area.

The "segment" is an arc length. \(\displaystyle \ \ \ \) That is incorrect.

A circular segment is an area of a circle informally defined as an area which is "cut off" from the rest of the circle by a secant or a chord.

Thank you for the correction, lookagain.

Don't need references; I believe you.
