Question

Please help me with this

Answer 1

Answer:

CD= 34

Step-by-step explanation:

As CD is the diameter the circle divides to half and point E is on the circle ∴∠CED =90° (angle of a semi circle)

as CD is the diameter it would be the lengthiest of all ∴ CD is hypotenuse

so $CD =\sqrt{16^{2} + \sqrt{30^{2} } } }$

= CD=$\sqrt{256+900}$

=CD=$\sqrt{1156}$

∴CD=34
