Question

A circle has a radius of 6 cm.

Answer 1

Yes I agree with the answer

Answer 2

Answer:

$1.5\pi$ cm

Step-by-step explanation:

A central angle measuring $45^\circ$ is $\frac{45^\circ}{360^\circ}=\frac{45}{360}$, or $\frac{1}{8}$ of the entire circle. The circumference of the circle is given by the formula $2\pi r$, which is $12\pi$.

Then, the length of an arc measuring $\frac{1}{8}$ of the entire circle is $12\pi\cdot\frac{1}{8}=1.5\pi$ cm.
