Hello There!
To find the Area of a circle, you'll need to follow this formula
A=[tex] \pi [/tex]r²
You'll use 3.14 for pi and the radius, you'll need to divide 16 by 2 to get 8 for the radius. Now you'll need to power 8 by 2 to get 64. Now you'll need to multiply 3.14 by 64 to get 200.96 as the Area of the circle
I hope this helps!
