Answer 1

Answer:

The circumference of the yellow circle is $9\pi$ or $28.27cm^2$ approximately, the circumference of the blue circle is $6\pi$ or $18.85m^2$ approximately, the circumference of the green circle is $80\pi$ or $251.33mm^2$ approximately, the circumference of the red circle is $5\pi$ or $15.71cm^2$ approximately, and the circumference of the pink circle is $7\pi$ or $21.99cm^2$ approximately.

Step-by-step explanation:

To find the circumference of a circle, you need to multiply the diameter of the circle and multiply it by $\pi$. In this case, the circumferences of the yellow circle are $9\pi$ or approximately $28.27cm^2$, the circumference of the blue circle is $6\pi$ or approximately $18.85m^2$, the circumference of the green circle is $80\pi$ or approximately $251.33mm^2$, the circumference of the red circle is $5\pi$ or approximately $15.71cm^2$, and the circumference of the pink circle is $7\pi$ or approximately $21.99cm^2$.
