Answer 1

The sum of areas of circle C and circle D is 98$\pi$ square units, it is obtained from the attachment.

Step-by-step explanation:

The given is,

                For the above question diagram is missing, so i attach the diagram

                C, D points in the attachment is the center of circle C and D

                Radius of circle C and D is 7 units

Step: 1

               Formula for area of circle,

                            $A=\pi r^{2}$..............................(1)

               Where, r - Radius of circle

Step: 2

              Area of circle, C

              Radius of circle C, r = 7 units

              Equation (1) becomes

                          $A_{C}=\pi (7)^{2}$

                          $A_{C} = 49\pi$ square units

              Area of circle, D

              Radius of circle D, r = 7 units

              Equation (1) becomes

                          $A_{D}=\pi (7)^{2}$

                          $A_{D} = 49\pi$ square units

Step: 3

              Sum of areas of circle C and D,

                                  = Area of circle C + Area of circle D

                                  = 49$\pi$ + 49$\pi$

                                  = 98$\pi$ Square units

Result:

          The sum of areas of circle C and circle D is 98$\pi$ square units, it is obtained from the attachment.
