Respuesta :
221.56, because in order to get the area of a circle, you must use this formula: area = (pi divided by 4) x diameter squared.
In this case, area = (3.14 / 4) x (16.8 x 16.8)
In this case, area = (3.14 / 4) x (16.8 x 16.8)
Answer:
Area of circle is 221.56 units ² .
Step-by-step explanation:
Formula
[tex]Area\ of\ circle = \pi r^{2}[/tex]
Where r is the radius of the circle.
As given
The diameter of a circle is 16.8 unit.
[tex]Radius = \frac{Diameter}{2}[/tex]
[tex]Radius = \frac{16.8}{2}[/tex]
Radius = 8.4 units
[tex]\pi = 3.14[/tex]
Putting all the values in the formula
[tex]Area\ of\ circle = 3.14\times 8.4\times 8.4[/tex]
= 221.56 units² (Approx)
Therefore the area of circle is 221.56 units ² .
