C. 17.9
Step-by-step explanation:
First you have to find the area of the circle, to then subtract it from the area of the square around it.
To get the area of the circle you must take the radius(half of the diameter) and square it. 3^2 is 9. Then you mutiply that by Pi( 3.14). Which is 7.07.
Next you have to subtract that from the area of the square deck.
25-7.07=17.9
