Answer:
Option C 
Step-by-step explanation:
we know that
The area of a circle is equal to
we have
substitute
Remember that
degrees subtends the complete area of the circle
so
by proportion
Find the area of the blue sector for an angle of 
degrees
You know the triangle has a base of 6 meters, and that the formula to find the area of a triangle is 1/2bh or one-half of the base times the height. So, you would plug in 9 meters squared=one half of six times h, or 9m^2=1/2(6)*(h). In simplifying this, you would get 3h=9m^2. Divide both sides by three and get h=3. Hope this helps, and if you need any further explanations, please let me know!
