Given that the diameter of the circle is 3 centimeters.
We need to determine the area of the circle.
Radius of the circle:
The radius of the circle is given by
[tex]r=\frac{d}{2}[/tex]
[tex]r=\frac{3}{2}=1.5 \ cm[/tex]
Thus, the radius of the circle is 1.5 cm
Area of the circle:
The area of the circle can be determined using the formula,
[tex]A=\pi r^2[/tex]
Substituting [tex]\pi=3.14[/tex] and [tex]r=1.5[/tex], we get;
[tex]A=(3.14)(1.5)^2[/tex]
[tex]A=7.1 \ cm^2[/tex]
Thus, the area of the circle is 7.1 cm²
Answer:
About 28.27
EXPLANATION:
Formula for area of circle is: πr^2
R= 3, given in the question
3^2 = 9
Answer 9 π = about 28.27
Hope this helped!
