Answer:
[tex]221.69952[/tex] [tex]cm^{2}[/tex]
Step-by-step explanation:
[tex]A=\pi r^{2}[/tex]
[tex]r=d/2\\r=16.8/2\\r=8.4[/tex]
[tex]A=3.142 \times 8.4^{2}[/tex]
[tex]A=221.69952[/tex]
Solution,
diameter=16.8 cm
radius=8.4 cm
Area of circle= pi r^2
= 3.142*(8.4)^2
=221.69952 cm^2
Hope it helps
Good luck on your assignment
