A company’s logo was designed using circles of 3 different sizes . The diameters of two of the circles are shown .

D . 254.34

Step-by-step explanation:

From the diagram,

the diameter of the big circle = 6 cm, and the diameter of the bigger circle = 12 cm.

So,

the diameter of the biggest circle = diameter of the big circle + diameter of the bigger circle

                                                    =  6 + 12

                                                    = 18 cm

Area of a circle can be determined by;

                  A  =  

where: is a constant of value ≅ 3.14, 'A' is the area and 'r' is the radius of the circle.

The biggest circles has a radius of

                                             =  

                                             = 9 cm

Thus, the area of the biggest circle =

                                                          =  3.14 ×

                                                         = 3.14 × 81

                                                        = 254.34

The area of the biggest circle is 254.34 .
