Answer 1

Answer:

In the first diagram,the length of the side of the sector of a circle is given.

According to there radius the π is being parted by 1/3. which makes

$\frac{1}{3} \pi\times radius$

Instead of

$2\pi \times r$

because it is 1/3 of the radius .

then we have to put the values in the r or radius to get the area of each and then add them to get its total area
