Multiply each term in the parentheses by 3. Your answer is 6a - 12b
Point D is the midpoint of the outer circle that we aim to find the area of
The circle has a diameter of WZ and radii of WC and CZ
We know that YZ=YD=10 cm
Let DC be

and CY be

The radius of the outer circle can be written as

or

which we can equate to find the value of





Therefore, the radius of the circle is

And hence the area of the circle is

=324
