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

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.
