Answer:

45 square centimeters


Step-by-step explanation:

The shaded region is  [tex]\frac{1}{6}[/tex]  of the whole circle. That means, the shaded region is 1 part of 6 parts in the circle.

Shaded region has area of 7.5 square centimeters. This is 1 part.

So, the area of 6 parts would be  [tex]7.5*6=45[/tex] square centimeters.

6 parts IS the WHOLE circle, hence, the area of the circle is 45 square centimeters.
