Find the radius of a circle with a circumference of 45pi centimeters

JulsSmile [24]

Answer:

<h2>The radius r = 22.5 cm</h2>

Step-by-step explanation:

The formula of a circumference of a circle:

$C=2\pi r$

r - radius

We have the circumference

$C=45\pi\ cm$

Substitute:

$2\pi r=45\pi$ <em>divide both sides by π</em>

$2r=45$ <em>dvide both sides by 2</em>

$r=22.5\ cm$

JKL is similar to PQR

so they want PR

JKL is similar to PQR

So PR is similar to JL

And they also give us the sides KL and QR

JKL is similar to PQR

Both of those sides are similar, so we can form a proportion.

$\sf { \frac{PR}{JL} = \frac{QR}{KL} }$

Plug in the numbers:

$\sf { \frac{PR}{6} = \frac{15}{9} }$

Cross multiply:

$\sf{ PR \times 9 = 6 \times 15}$

Isolate PR

$\sf{ PR = \frac{6 \times 15}{9}}$

Simplify it

$\sf{ PR = 10}$

So your final answer is

$\boxed{\bf{10 centimeters}}$
