in the diagram, there is 2 small circle in a big circle and what they are asking is what is the area of the shaded rigion when the radius of the larger circle is 6.
what i did was since you know what the radius of the large circle is 6, the area of a circle is "pie r square". so 6x6=36 and x pie is 36pie.
radius of the smaller circles are 3 beacuse 6 is there "d". so 3x3=9pie. and there is 2 circle so times to is 18pie.
use the big circle area to minus the 2 small circles. so 36pie minus 18pie is 18pie. so the answer is 18pie which is "d".
