Answer 1

Answer:8.99 cm

Step-by-step explanation:

Answer 2

Answer:

$8.995$cm

Step-by-step explanation:

The circumference formula is: $C=2\pi r$

We are given the circumference, which is 56.52cm.

The question wants us to find the radius, r.

To achieve this, we must solve for r.

Plugging in 56.52 for C we get:

$56.52=2\pi r$

Dividing both sides by $2\pi$, we find r:$8.995$

$\frac{56.52}{2\pi } =r$

$8.995$≈$r$

If you want to round it up, you can round it to 9cm.
