Two similar circles are shown. The circumference of the
larger circle, with radius OB, is 3 times the circumference of
the smaller circle, with radius OA.
Radius OB measures x units. Which expression represents
the circumference of the smaller circle with radius OA?

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
