Answer:

C = πd

The area of a circle can be found by multiplying pi ( π = 3.14) by the square of the radius.

If a circle has a radius of 4, its area is 3.14*4*4=50.24.

If you know the diameter, the radius is 1/2 as large.

Ray Of Light [21]
The width would be 236 and the lengths would be 118

Use the equations 2L+W=472 and W*L=MAX
Change the first equation to W=472-2L and plug this into the other equation
(472-2L)(L)=MAX
472L-2L^2=M (take derivative)
472-4L=0 (set to 0 to find the max value)
4L=472 
L=118 
Plug into original to get W=236

Hope this helps!
