The circle with diameter of 24 means that 2
r = 24.
Solving for r, we getr=24.
Dividing both sides by, we get r=24/
.
The area of the full circle is times 24 squared over 
. The being multiplied cancels out, meaning that 24 squared over is the area of the full circle. 24 squared is 576, and dividing by 16 we get 
as the answer.
Solving for r, we get
Dividing both sides by
The area of the full circle is
