Answer:
24.62 in^2
Step-by-step explanation:
The area of a circle is A=pi*r^2
Circumference is C=2*pi*r
Given a circumference of 17.6 inches, we get:
17.6=2*3.14*r
17.6=6.28r
2.8025=r
Given a radius of roughly 2.8 inches, we can find the area:
A=3.14*2.8^2
A=3.14*7.84
A=24.6176
So the area is around 24.62 in^2
