Given:
length=16
width=12
radius=4.5
So total length is:
length of half circle is:
circumference of circle:
[tex]\begin{gathered} C=2\pi r \\ \text{half circle=}\frac{2\pi r}{2} \\ =\pi r \end{gathered}[/tex]
[tex]\begin{gathered} r=4.5 \\ =\pi r \\ =\pi(4.5) \\ =14.137 \end{gathered}[/tex]
For there sides of circle is:
[tex]\begin{gathered} \text{length}+\text{width}+\text{width} \\ =16+12+12 \\ =40 \end{gathered}[/tex]
for circle side length is:
[tex]\begin{gathered} =16-(\text{diameter of circle)} \\ =16-(2\times4.5) \\ =16-9 \\ =7 \end{gathered}[/tex]
So total length is:
[tex]\begin{gathered} =14.137+40+7 \\ =61.137 \\ \approx61 \end{gathered}[/tex]
Approximate length of the edge that Tasha will cover with tile is 61.
