The circumerfence of a circle can be found use the equation C=2r. So since we are given the circumerce we need to rearrange the eqaution to it looks like =r. when we do this out we find that the radius equals 4.8.
If you know the measurements of 2 sides not the height , you can apply Pythagorean theorem to find the height. Square root of the sum of the squared sides
