ABCDEis a circle O . The diameter   AC is extended to the point F so that CF=16cm. The line BF is the tangent to the circle at B and FDE is a straight line such that FD=18cm andDE=14cm . The radius of the circle is rcm . Calculate(a) the length in cm of  FB(b) the value of  r .

Given circle EE with diameter start overline, C, D, end overline CD and radius start overline, E, A, end overline EA . start overline, A, B, end overline AB is tangent to EE at AA. If E, A, equals, 8EA=8 and E, B, equals, 17EB=17, solve for A, BAB. Round your answer to the nearest tenth if necessary. If the answer cannot be determined, click "Cannot be determined."
