d/2=r
big diameter=20.4, so radius i 20.4/2=10.2cm
small is 10.8/2=5.4
so
big-small
pi10.2^2-pi5.4^2
pi(104.04-29.16)
pi(74.88)
using 3.14=pi
235.1232 cm^2
answer is B

<span>Hello, Codymitchell52
I will be solving log(6x+5)=2
</span><span>log (6x + 5) = 2
6x+5 = 10^2
6x+5 = 100
6x = 95
x = 95/6
x = 15.833 </span>
