Question

What is the sum of the areas of circle C and circle D?

7tt units
7 cm
141 units
491 units
981 units

Answer 1

The area of a circle is r^2 x PI

Each circle is shown with a radius of 7cm.

The area for one circle would be 7^2 x PI = 49PI

The area for both circles would be 49PI + 49PI = 98PI units^2
