Answer:
Area =[tex]3617.28 \ ft^2[/tex]
Step-by-step explanation:
Radius of bi circle = 12 + 24 = 36
Radius of small circle = 12
Area of shaded region = area of big circle - area of small circle
[tex]= \pi \times 36^2 - \pi \times 12^2\\\\= \pi \times (36^2 - 12^2)\\\\ = \pi \times 1152\\\\= 3617.28 \ ft^2[/tex]
