Answer 2

The true statements are following,

• The area of a circle depends on the length of the radius.

• The area of a sector depends on the ratio of the central angle to the entire circle.

Area of circle :

The area of circle is given as,

                          $Area =\pi *r^{2}$

Where r is radius of circle.

From above relationship, it is observed that The area of a circle depends on the length of the radius.

The area of sector which making central angle $\theta$ at the center is,

                   $Area=\frac{\theta}{360} *\pi r^{2}$

It is observed that the area of a sector depends on the ratio of the central angle to the entire circle.
