Find the area of a sector given the diameter is 25 cm and the length of the arc is 52cm.

Answer 1

So, the diameter is 25 cm. First calculate the circumference, which is 25pi in this case. Now the ratio of the circumference and the arc length should be the same as the area of the sector:area of the entire circle.

Answer 2

hi,
Do you know about the radiant ?

Answer 3

If you know about radiant value of an angle I show u how to calculate this easily

Answer 4

The area of the circle is πr^2. So the following equation should be used:

\[\frac { Arc\quad length }{ Circumference } =\frac { Area\quad of\quad sector }{ Area\quad of\quad circle } \]
