Step-by-step explanation:
Answer:
π(8)²=64π
Step-by-step explanation:
Area = Pi times radius squared
We know the Diameter is 16 so the radius must be 8.
8 squared = 64, then we multiply pi when you get your answer.
8 x 64
=64 x 2 x 4
=128 x 2 x 2
=256 x 2
=512
$2.93/$42= about 7% tax
$58*7%= $<span>4.06 in tax</span>

areacircle=pir^2
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
