18.84

Since the formula of circumference is C = 2 pi r or C = pi times diameter, you can conclude that the circumference is 18.84.

Assuming that pi is 3.14 in this case rather than the full pi or just in terms of pi.

Hope this helps!

Find the radius of a circle with an area of 380 in².

Likurg_2 [28]

Answer:

11 inches

Step-by-step explanation:

The area of a circle can be found using:

$a=\pi r^{2}$

We already know that the area is 380, so we can substitute 380 in for a.

380= $\pi r^2$

Now, we need to find the radius. To do this, we need to get r by itself

First, divide both sides by pi

$380/\pi =\pi r^2/\pi$

120.95775675=r^2

Since r is being squared, we need to take the square root of both sides

$\sqrt{120.95775675}=\sqrt{r^2}$

10.9980796846=r

If we round to nearest whole number, our radius is 11 inches
