In the diagram, XZ is the diameter of a circle’s radius \(\frac{5}{2}\). If XY is 4cm, then the area of the triangle XYZ is
- 12cm2
- 28\(\frac{1}{2}\)cm2
- 16cm2
- 10cm2
-
6cm2
The correct answer is: E
Explanation
Area of the triangle XYZ = \(\frac{1}{2}\)bh = \(\frac{1}{2}\)ZY x XY
= \(\frac{1}{2}\) x 3 x 4
= 6cm2.
