Question

SU is tangent to a circle with center T at point R. If SR = 12 inches and ST = 19 inches, what is the approximate radius of the circle?

Answer 1

Since tangent is perpendicular to radius, triangle SRT is right angled at R. Using Pythagoras theorem, RT = \[\sqrt{ST ^2 - SR^2}\].

Answer 2
