The circumference of a circle is 64 pi cm. Find the diameter, the radius, and the length of an arc
of 190°

Answer:
length of arc:
[tex] \frac{190}{360} \times 64\pi[/tex]
[tex]33.8\pi \: cm[/tex]
diameter of circle
[tex]2\pi {r}^{} = 64\pi[/tex]
[tex] {r}^{} = \frac{64\pi}{2\pi} [/tex]
[tex] {r}^{} = 32cm[/tex]
diameter of circle
= 2r
= 2(32)
= 64 cm
The radius of the given circle is 32 cm and the diameter of the circle is 64 cm.
We have given that,
The circumference of a circle is 64 pi cm.
[tex]\ length \ of \ arc=\frac{190}{360}\times 64\pi\\ length \ of \ arc=33.8\pi[/tex]
[tex]\ circumference \ of \ the \ cirecle=2\pi r[/tex]
Diameter of the circle:
[tex]2\pi r=64\pi[/tex]
[tex]r=64\pi/2\pi \\r=32cm[/tex]
diameter of circle= 2r
Therefore use the above value we get,
= 2(32)
= 64 cm
Therefore the radius of the given circle is 32 cm and the diameter of the circle is 64 cm.
