Answer:
% area of the shaded region = 33%
Step-by-step explanation:
Radius of the middle circle = 7 cm
Radius of the inner circle = 4 cm
Area of the middle circle = πr²
                                           = π(7)²
                                           = 49π
    Area of the inner circle = π(4)²
                                            = 16π
Area of the shaded region= 49π - 16π
                                             = 33π
Area of the outermost circle = π(10)²
                                                = 100π
% area of the shaded region = 
                                                 = 
                                                 = 33%
Therefore, area of the shaded region is 33% of the complete logo.

Answer:
C. 2448π units³
Step-by-step explanation:
V = π·r²·h
= π·12²×17
= 144×17·π
= 2448π units³
