Answer:

below

Step-by-step explanation:

Radius of the middle circle = 7 cm

Radius of the inner circle = 4 cm

the area of the biggest circle is= π10² = 100πcm²

the area of the medium circle is= π7² = 49πcm²

the area of the smallest circle is= π5² = 25πcm²

Area of the inner circle = π(4)²= 16π

Area of the shaded region= 49π - 16π = 33π

% area of the shaded region =  33%

Therefore, area of the shaded region is 33% of the complete logo.
