Question 636358
I have a 10ft in diameter oval pool
 If I build a 3 ft walkway around it what is the square footage of the walkway?
:
The overall diameter, including the walkway, will be 16 ft, then
overall radius = 8 ft, (pool radius = 5 ft)
:
Walkway area = overall area - pool area
ww.a = {{{(pi*8^2)}}} - {{{(pi*5^2)}}}
ww.a = 122.522 sq/ft
