Answer:
The area of the circle is 254 square unit. ( approx )
Step-by-step explanation:
Given,
The diameter of circle = 18 unit,
⇒ The radius of the circle = [tex]\frac{18}{2}[/tex] = 9 unit,
Since, the area of a circle,
[tex]A=\pi r^2[/tex]
Where r is the radius of the circle,
Thus, the area of the circle is,
[tex]A=\pi (9)^2[/tex]
[tex]=3.14\times 81[/tex] ( [tex]\pi[/tex] = 3.14 )
[tex]=254.34\text{ square unit}\approx 254\text{ square unit}[/tex]
The area of circle is nearly 254 square unit.
Area of Circle:
The area of circle is given as,
[tex]Area=\pi *r^{2}[/tex]
Where r is radius of circle and [tex]\pi =3.14[/tex]
Given that, Circle diameter is 18
So that, radius [tex]r=\frac{18}{2}=9cm[/tex]
Area of circle is,
[tex]Area=3.24*9^{2} \\\\Area=3.14*81=254.34[/tex]
The area of circle is nearly 254 square unit.
