for fun question, I saw this on the internet and saw the solution, explain logic. diagrams are encouraged, please give radical form and aprox form
find the area of the shaded area (units are inches)
show all work

Respuesta :

A = lw - 2πr²
A = (20)(10) - 2(3.14)(5)²
A = 200 - 2(3.14)(25)
A = 200 - 2(78.5)
A = 200 - 157
A = 43 in²
Solutions 

Formula = 

Area = 
π × r^2 

[tex]Area = lw - 2pir^2 Area = (20)(10) - 2(3.14)(5)^2 Area = 200 - 2(3.14)(25) Area = 200 - 2(78.5) Area = 200 - 157 Area = 43 in^2 [/tex]
