How do I do this? Please helppp!!!

Step-by-step explanation:
1. find the diameter
2. use the formula (a=3.14r^2) ---- (a=area) (3.14=pi) (r=radius) (^2=squared)
using the formula is the main step. hope this helps.
Answer: I got 292.72 mm
Step-by-step explanation: Area of Circle formula: [tex]A=\pi r^2[/tex]
Area of the square formula: A= [tex]A= l^{2}[/tex]
Circle:
A=3.14*9.8^2
A= 301.71 mm
Square:
A= 3^2
A=9 mm
Then you have to subtract them-
301.71 - 9 = 292.72 mm
My answer is not accurate, but it's so close
