Answer:
D. 59.66
Step-by-step explanation:
The formula is A = [tex]\pi r^{2}[/tex\ Also the radius is half of the diameter. and [tex]\pi[/tex] = 3.14
so we need to find the area's
9 x 9 = 81
81 x 3.14 = 254.34
Next circle.
10 x 10 = 100
100 x 3.14 = 314
Now to find the difference.
314 - 254.34 = 59.66
59.66
