Answer:

725.71 cm

Step-by-step explanation:

Using the attached diagram :

Diameter of inner circle = 26

Radius of inner circle = 26/2 = 13

Radius of entire circle = 13 + 7 = 20

The Area of a circle = πr²

Area of inner circle = π13² = 169π

Area of entire circle = π20² = 400π

Area of shaded portion :

Area of entire circle - Area of inner circle

400π - 169π = 231π = 725.71 cm
