The hypotenuse of this triangle will be the radius of the circle.Using the Pythagorean theorem:r2=92+122Calculating the squares of the legs:r2=81+144Adding these values together:r2=225Taking the square root of both sides to find the radius:r=\|225=15cmSo, the radius of the circle is 15 cm15cm.<img src="/styles/default/xenforo/smilies/default/P.gif"  class="smilie" loading="lazy" alt=":P" title=":P    :P" data-shortname=":P" /></blockquote>
