Answer:
• The radius of the circle is 54.6 cm.
,
• The circumference of the circle is about 171.53 cm.
Explanation:
Given the radius of a circle = 27.3 cm
Diameter
The diameter of a circle is twice the length of the radius.
[tex]\begin{gathered} Diameter=2\times Radius \\ =2\times27.3 \\ =54.6\;cm \end{gathered}[/tex]
The radius of the circle is 54.6 cm.
Circumference
The circumference of a circle with radius, r is calculated using the formula:
[tex]C=2\pi r[/tex]
Substitute r=27.3 cm:
[tex]\begin{gathered} C=2\times\pi\times27.3 \\ =171.53095889 \\ \approx171.53\;cm \end{gathered}[/tex]
The circumference of the circle is about 171.53 cm.
