Answer:
Area of circle is 221.56 units ² .
Step-by-step explanation:
Formula
\(Area\ of\ circle = \pi r^{2}\)
Where r is the radius of the circle.
As given
The diameter of a circle is 16.8 unit.
\(Radius = \frac{Diameter}{2}\)
\(Radius = \frac{16.8}{2}\)
Radius = 8.4 units
\(\pi = 3.14\)
Putting all the values in the formula
\(Area\ of\ circle = 3.14\times 8.4\times 8.4\)
= 221.56 units² (Approx)
Therefore the area of circle is 221.56 units ² .
