Answer:
The area of the circle is 136.78 cm².
Step by step explanation:
The area of a circle is
\(A=\pi r^2\) ....(1)
Where, r is the radius of the circle.
The diameter is two of is radius.
\(d=2r\)
It is given that the diameter of circle is 13.2 cm.
\(13.2=2r\)
\(r=\frac{13.2}{2}=6.6\)
Substitute r=6.6 and π=3.14 in equation (1).
\(A=3.14\times (6.6)^2\)
\(A=136.7784\)
\(A=136.78\)
Therefore the area of the circle is 136.78 cm².
