As you can see in the picture, the diameter is 3 cm. The formula to find the area of the circle is
[tex]\begin{gathered} A=\pi\cdot r^2=3.14\cdot r^2 \\ r=\text{ radius} \\ d=\text{diameter} \\ r=\frac{d}{2} \\ A=3.14\ast(1.5)^2 \\ A=7.065cm^2 \end{gathered}[/tex]
And the formula of the circumference is:
[tex]\begin{gathered} P=\text{perimeter } \\ P=\pi\cdot d \\ P=3.14\ast3 \\ P=9.42\text{ cm} \end{gathered}[/tex]
So the answer is Area = 7.065 cm2 and Circunference= 9.42 cm
